There can be many such sensor nodes but only two such nodes are used here. The receiver includes 433MHz ASK RF receiver module, real-time clock (RTC) module, and Arduino Nano. Both sensor nodes ...

The left leg of LM35 is power, we connect it to the 5v pin on Arduino with a red wire, the right leg is ground end, we connect it to GND pin on Arduino with a black wire, the middle leg is value out, ...

Here are the steps I took to install Node-RED on my Raspberry Pi B, and then to wire it up to a DHT22 humidity and temperature sensor to log the conditions in my office. It’s based on my work last ...

Ultrasonic sensor . Node-RED is not only for the Raspberry Pi. It can also be used (although limited) with the Arduino and ESP32 processors, or with a combination of the Raspberry Pi and the Arduino, ...

This isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.
