Product details
Product description
Description This capacitive soil moisture sensor differs from most of the resistive sensors on the market, using capacitive sensing principle to detect soil moisture.
It avoids the problem that the resistance sensor is easy to corrode and greatly prolongs its working life.
Size: 193.5*29.4mm Comparison before and after the soil test module G301 upgrade: (Upgrade time: April 16, 2020) 1. Changed from the original ESP32 module to a separate ESP32 chip.
2. The lithium battery was changed from the original 18650 to a 500MA lithium battery.
(battery not includes) 3. The charging IC was changed from the original TP5400 to TP4054. 4. Change the original MICR carrier to TYPE-C.
5. The original normal power supply mode is changed to the key sleep wake-up mode (or the customer can make a timed wake-up).
6. The size of the board is 45mm smaller than the previous length, and the width is increased by 2.54MM.
7. Change from the original DHT12 (temperature and humidity sensor) to DHT11 Add part: 1. Added sleep button wake-up function (IO35) 2. Added test soil salinity function (CD4060BM TL034IDR) 3. Added light (BH1750FVI) strength test 4. Reserved external device expansion (single bus serial port IIC----21~22) Advantage: The battery life is much longer than before.
In the case of testing moisture, you can test the soil's salt and photosynthetic absorption, reasonable fertilization and proper sun exposure.
Working current: 150MA Sleep current: 220UA Package included: 1 x Higrow ESP32 WiFi + bluetooth + DHT11 Soil Temperature And Humidity Sensor Module
