In this project I develop an Arduino library to read the data generated by the DHT11 Humidity and Temperature sensor to send it continuously to the ThingSpeak cloud services with an AZDelivery ESP8266 ESP-12F NodeMCU Lua Amica V2. There are many libraries ready to use to read DHT11 sensor data. WebMay 6, 2024 · The longer the wire to the sensor, the lower the resistor should be. The wire acts as a capacitor and the current flowing through the resistor needs to "fill the wire". If the wire is longer it takes longer to fill, unless the resistor is smaller, then more current can flow. The faster the wire fills up, the more square the signal will be. grassland limited
