LILYGO® T-Higrow ESP32 BME280 talajnedvesség modul
ESP32 alapú WiFi és Bluetooth képes, akkumulátor töltásvezérlőt tartalmazó lapka. A taljszenzor kapacitív elven működik, ezzel nagyobb pontosság érhető el. A környezeti szenzor egy BME280.
LILYGO® T-Higrow ESP32 Soil Tester BME280 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.
