WebMar 1, 2024 · Alison Asks: Combining code for two sensors in one programming We need to read two readings of Humidity and Temperature from 2 different locations. We can run each of them separately but we don't know how we can make them work simultaneously in one program. We are using a TH02 sensor that we... WebThis is the Arduino Mega with 3 Relays controlled by values from a photoresisor and Humidity & Temperature sensor (DHT11). In this case if the Temperature is above 25C the relay will turn on the cooling fan, and will turn off if the value is below 25C.
WebJan 6, 2024 · By some reason when using VirtualWire library and using vw_setup(2000) caused the readings from humidity sensor to fail (dht11 start condition 1 not met). I looked at datasheet and changed a the times how the MCU starts to talk with the sensor. The code is based from this post.
