It is a small box that houses the sensor DHT22 and the uC ESP32 for it, it also includes an OLED screen that shows the temperature and relative humidity, it also includes the 18650 battery with its respective charge controller and also allows IoT mode.Download...
I've been trying to make a temperature sensor based on the ESP32-C3-DevKitM-1 and using a driver from GitHub. I already tried 2 and both timeout trying to read from the sensor. Once I plug it into an Arduino, with the same pin configuration, it works. ...
sensor = dht.DHT22(Pin(16)) # 使用 DHT22 型號 # 如果使用 DHT11,可以將上面一行替換為 # sensor1 = dht.DHT11(Pin(16)) # 無限迴圈,每隔一段時間測量溫度和濕度 while True: sensor.measure() # 開始測量溫度和濕度 temp = sensor.temperature() # 取得測量的溫度 hum = sensor.humidity() # ...
In this tutorial we will check how to get the minimum sampling period of the DHT22 and how to use it to make some temperature measurements without crossing the maximum sampling rate the sensor suports. We are going to usethislibrary to interact with the DHT22 from the ESP32, using the A...
