ALG 3000mAH 18650 battery could make ESP32 working.
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.

S18B20 waterproof temperature sensor is used for t-higrow and t-watch with t-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 fish tank when raising fish. Of course, it can also test other temperatures as long as you want.
