These are demos of DHT21 and DHT22 relative humidity-temperature sensors using interrupt and timer of an AVR micro. Interrupt + timer based method don't block program sequence unlike polling methods and so the CPU can do other tasks. Falling edge interrupt is used to detect the output from the sensor and a timer detects pulse widths.
