 This code can be combined with the code from the DHT-22 and the DS18B20s such that the sensors are only powered when they are supposed to measure and are switched off again afterwards. This code can be combined with the code from the DHT-22 and the DS18B20s such that the sensors are only powered when they are supposed to measure and are switched off again afterwards.
  
-The sensors and the shift register need to be connected like explained in their pages, respectively. Additionally, the VDD pin of the DHT-22 must be connected to QB of the shift register and the VDD of both DS18B20s must be connected to QC. Furthermore, if a red LED with a 330Ω resistor in series is connected to QA, it indicates when the sensors finish their measurements with a short blink.+The sensors and the shift register need to be connected like explained in their pages, respectively.

 During this test, all sensors were in equilibrium, measuring the room temperature during a rather hot summer day, and all results are close together, indicating that the sensors are working properly. During this test, all sensors were in equilibrium, measuring the room temperature during a rather hot summer day, and all results are close together, indicating that the sensors are working properly.
