Sending sensor data wireless (433MHz) with an Attiny85 or Attiny45 with Manchestercode – Arduino, ESP8266, ESP32 & Raspberry Pi stuff

In an earlier article I described how to send RF/wireless data between two Attiny85 chips with a 433 MHz transmitter/Receiver pair. Now I will  give a more practical program that sends  3 variables from an LDR and a DHT11 sensor. The connections are simple The transmitter is connected to D0 (pin 5). The DHT11 sensor…
