12V to 5V Sensor Circuit

12V to 5V Sensor Circuit with DHT11

A number of sensors are powered via 12 Volts. Some, however, need 5 Volts.  To power a remote DHT11 temperature sensor, I created a 12V to 5V sensor circuit. This is the wiring diagram: Get the Fritzing code for it HERE.       The DHT11 needs 5 volts,  ground and data. It plugs into …
