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 …

Arduino Weather Station


With just a few sensors, one can determine a lot about the weather.                 The BMP085 can be used to sense barometric pressure and temperature and the DHT11 can be used to sense humidity and also temperature. Here is what they look like attached to a mini breadboard: …
