TTGO T-Higrow Esp32Wroom Introduction
This product comes with Wifi Bluetooth Humidity Photometric Electrolyte Sensor Unsoldered. 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.S18B20 waterproof temperature sensor is used for this product and t-watch with the t-grove interface. For example, it can be used to test the temperature and humidity of flowerpot soil and environment, as well as the water temperature of fish tanks when raising fish.
- 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 sensors, it already includes the function of DHT11, we have removed the DHT11 sensor on the BME280 version to reduce costs.
