This is a TTGO T-Higrow BME280 Wifi Bluetooth-Unsoldered (Without Humidity Photometric Electrolyte Sensor). The 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. 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 fish tanks when raising fish. Of course, it can also test other temperatures as long as you want.
