If we are looking at the 4-pin sensor the extra pin is a NC pin, and it has no functions. The pin diagram of both the module and the sensor is shown below. DHT22 Module Pinout The diagram below shows ...

Circuit Diagram of DHT11 Module The DHT11 consists of a pull-up resistor which is added to the data pin. A single led is used with a 1k current limiting resitor and capacitor is used to filter the ...

I simulated a circuit for nanowires, designed the schematic and a PCB board. Furthermore, it is planned to write code for the Arduino board to transmit data to the PC. Development of the data ...

A temperature and humidity sensor. I use the BME680 together in the mmWave radar sensor configuration to create a powerfull all in one sensor. For the temperature and humidity only configuration, I ...

Internet of Things (IoT) and building automation systems require more wireless sensor end nodes, but their power constraint is a major obstacle. The end nodes are battery-powered and need replacement ...

We’ve previously tested the SNZB-02 Zigbee temperature and humidity sensor with the SONOFF NSPanel Pro smart panel, but ITEAD has now launched the SONOFF SNZB-02D that integrated the same features ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...
