Many gardeners and growers water on instinct \u2014 but too much or too little water is the most common cause of poor plant growth.  <strong>ECOWITT WH52 wireless soil moisture sensor<\/strong> gives you concrete measurement data so you can make smarter decisions. With built-in EC measurement and a soil temperature sensor in one device.<\/p>\n<h2>What does the ECOWITT WH52 measure?<\/h2>\n<h3>\ud83c\udf0a Soil moisture (0\u2013100%)<\/h3>\n<p>The WH52 uses <strong>FDR technology<\/strong> (Frequency Domain Reflectometry) \u2014 the most reliable method for soil moisture measurement, independent of soil type. Set threshold values in the app to get an alert when the soil becomes too dry or too wet. Never be caught out by wilted plants again.<\/p>\n<h3>\ud83c\udf21\ufe0f Soil temperature (-40\u00b0C to +60\u00b0C)<\/h3>\n<p>The built-in NTC thermistor measures the <strong>actual soil temperature<\/strong> at root depth \u2014 not the air temperature. Plant growth depends heavily on soil temperature: too cold in spring stops even the best plant. See exactly when the soil is warm enough for planting or sowing.<\/p>\n<h3>\u26a1 Electrical conductivity \/ EC (0\u201310,000 \u03bcS\/cm)<\/h3>\n<p>EC (electrical conductivity) is a direct measure of the <strong>concentration of soluble nutrients<\/strong> in the soil. Too low? A shortage of nutrition. Too high? Risk of salt damage to the roots. With the WH52 you make fertilising <strong>measurable and repeatable<\/strong> \u2014 no more guesswork.<\/p>\n<h2>Who is the ECOWITT WH52 for?<\/h2>\n<ul>\n<li>\ud83c\udfe1 <strong>Hobby gardeners<\/strong> who never want plants that are too dry or too wet again<\/li>\n<li>\ud83c\udf3f <strong>Vegetable gardeners<\/strong> who want to water and fertilise more precisely<\/li>\n<li>\ud83e\udeb4 <strong>House plant lovers<\/strong> who also measure outdoors in the garden<\/li>\n<li>\ud83c\udf3e <strong>Growers and smallholders<\/strong> who want to monitor several beds<\/li>\n<li>\ud83c\udfd7\ufe0f <strong>Greenhouse and vegetable growers<\/strong> who want to link soil data to irrigation<\/li>\n<li>\ud83c\udfe0 <strong>Home Assistant \/ home automation users<\/strong> \u2014 the GW1100 integrates natively with Home Assistant, MQTT and ecowitt.net<\/li>\n<\/ul>\n<h2>What is in the box<\/h2>\n<ul>\n<li>1\u00d7 ECOWITT WH52 soil moisture sensor (moisture + temperature + EC)<\/li>\n<li>1\u00d7 Ecowitt GW2000 WiFi gateway<\/li>\n<li>2\u00d7 protective cap (1 long + 1 short)<\/li>\n<li>1\u00d7 user manual<\/li>\n<li>\u26a0\ufe0f Battery <strong>not<\/strong> included \u2014 1\u00d7 AA battery required<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th>Specification<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Model<\/td>\n<td>ECOWITT WH52<\/td>\n<\/tr>\n<tr>\n<td>Measuring principle<\/td>\n<td>Frequency Domain Reflectometry (FDR)<\/td>\n<\/tr>\n<tr>\n<td>Soil moisture range<\/td>\n<td>0 \u2013 100%<\/td>\n<\/tr>\n<tr>\n<td>Soil moisture accuracy<\/td>\n<td>\u00b15%<\/td>\n<\/tr>\n<tr>\n<td>Temperature range<\/td>\n<td>-40\u00b0C to +60\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Temperature accuracy<\/td>\n<td>\u00b11\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>EC range<\/td>\n<td>0 \u2013 10,000 \u03bcS\/cm<\/td>\n<\/tr>\n<tr>\n<td>EC accuracy<\/td>\n<td>\u00b1100 \u03bcS\/cm (0\u20131000) \/ \u00b115% (1000+)<\/td>\n<\/tr>\n<tr>\n<td>Update interval<\/td>\n<td>70 seconds<\/td>\n<\/tr>\n<tr>\n<td>Wireless range<\/td>\n<td>100 m (open field)<\/td>\n<\/tr>\n<tr>\n<td>Frequency<\/td>\n<td>868 MHz (CE certified)<\/td>\n<\/tr>\n<tr>\n<td>Water resistance<\/td>\n<td>IP66<\/td>\n<\/tr>\n<tr>\n<td>Power supply<\/td>\n<td>1\u00d7 AA battery (not included)<\/td>\n<\/tr>\n<tr>\n<td>Battery life<\/td>\n<td>Min. 12 months<\/td>\n<\/tr>\n<tr>\n<td>Channels<\/td>\n<td>Max. 16 sensors per gateway<\/td>\n<\/tr>\n<tr>\n<td>Sensor dimensions<\/td>\n<td>148 \u00d7 86 \u00d7 25 mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Frequently asked questions<\/h2>\n<details>\n<summary><strong>Does the WH52 itself need a WiFi connection?<\/strong><\/summary>\n<p>No. The sensor communicates via an 868 MHz radio signal to the supplied GW1200 gateway. Only the gateway needs WiFi. This gives the sensor extremely low power consumption and makes the battery last well over a year.<\/p>\n<\/details>\n<details>\n<summary><strong>Which app do I use with the ECOWITT WH52?<\/strong><\/summary>\n<p>The free <strong>Ecowitt app<\/strong> (iOS and Android) or the web dashboard via <em>ecowitt.net<\/em>. Both are free and require no subscription. You see live values and historical graphs, and you can set alerts for thresholds that are too dry or too wet.<\/p>\n<\/details>\n<details>\n<summary><strong>Can I connect several WH52 sensors to one gateway?<\/strong><\/summary>\n<p>Yes \u2014 the GW2000 supports up to <strong>16 soil moisture sensors<\/strong> at the same time. Handy if you want to monitor several plots, beds or pots separately. Every sensor appears separately in the app with its own name and data.<\/p>\n<\/details>\n<details>\n<summary><strong>Does the WH52 also work indoors for house plants?<\/strong><\/summary>\n<p>Yes. Push the sensor into the potting soil and make sure the gateway is within WiFi range. For house plants you do not need to insert the sensor deeply \u2014 the measuring points sit near the top of the pin.<\/p>\n<\/details>\n<details>\n<summary><strong>Is the WH52 suitable for Home Assistant?<\/strong><\/summary>\n<p>Yes! The GW2000 integrates natively with <strong>Home Assistant<\/strong> via the Ecowitt integration. It also supports <strong>MQTT<\/strong>, Wunderground and ecowitt.net. Popular with home automation enthusiasts who want to link soil data to automatic irrigation.<\/p>\n<\/details>\n<details>\n<summary><strong>How deep should I insert the sensor?<\/strong><\/summary>\n<p>Insert it up to the <em>&#8220;MAX DEPTH&#8221;<\/em>marking on the housing. For garden beds a depth of 10\u201315 cm is recommended \u2014 the zone where most roots are active. The sensor then measures soil moisture, temperature and EC at the same root depth.<\/p>\n<\/details>\n<details>\n<summary><strong>What is a good EC value for my garden?<\/strong><\/summary>\n<p>For most garden plants and vegetables a healthy EC value lies between <strong>200 and 1200 \u03bcS\/cm<\/strong>. Demanding crops such as tomatoes and peppers thrive at 2000\u20134000 \u03bcS\/cm. With the WH52 you see immediately whether your soil is too poor or too salty, and when extra fertilising is needed.<\/p>\n<\/details>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li>\ud83c\udf0a <strong>Measures 3-in-1 wirelessly<\/strong>: soil moisture, soil temperature and electrical conductivity (EC) at the same time<\/li>\n<li>\ud83d\udcf1 <strong>Real time via app<\/strong>: view your data on your smartphone with the free Ecowitt app or the ecowitt.net dashboard<\/li>\n<li>\u2705 <strong>Complete package<\/strong>: includes the Ecowitt WiFi gateway \u2014 ready to use straight away, no extra hardware needed<\/li>\n<li>\ud83c\udf27\ufe0f <strong>IP66 waterproof<\/strong>: suitable for garden, greenhouse, vegetable patch and grow room \u2014 even in the rain<\/li>\n<li>\ud83d\udd0b <strong>12 months of battery<\/strong>: just 1 AA battery for a whole year of measuring<\/li>\n<li>\ud83d\udce1 <strong>100 metre range<\/strong>: ideal for a large garden, greenhouse or grow room<\/li>\n<\/ul>\n","protected":false},"featured_media":24001,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[114,707],"product_tag":[],"class_list":["post-23995","product","type-product","status-publish","has-post-thumbnail","product_cat-measuring-instruments","product_cat-vochtmeters","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n<title>Wireless Soil Moisture Sensor EC Temperature - ECOWITT WH52<\/title>\n<meta name=\"description\" content=\"Wireless soil moisture sensor for moisture, temperature and EC via app. Incl.
