LILYGO® T-Higrow ESP32 Soil Tester DHT11 BEM280 Garden Flowers Temperature Moisture Sensor WiFi Bluetooth Wireless Control Meter
T-Higrow Introduction
- This capacitive soil moisture sensor differs from most of the resistive sensors on the market, using the 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.
Note:
- Since BME280 already includes temperature and humidity sensor, it already includes the function of DHT11, we have removed the DHT11 sensor on the BME280 version to reduce costs.

T-Higrow can be used with T-Higrow and T-Watch with Grove interface.
For example：
- It can be used with T-Higrow to test the temperature and humidity of flowerpot soil and environment, as well as the water temperature of the fish tanks when raising fish. Of course, it can also test other temperatures as long as you want.
