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 digram for Digital Thermometer using Arduino and LM35 Temperature Sensor , is shown in the above figure. Make the connections carefully as shown in the schematic. Here 16x2 LCD unit is ...

Data Visualization: o Real-time temperature and humidity readings are sent to the serial monitor every second, providing a clear demonstration of sensor performance. Circuit Diagram The circuit ...

Problem statement: Develop the code in Arduino to interface an LM35 temperature sensor (Assume the sensor is connected to Arduino Analog pin A0) with an Arduino Uno and control the onboard LED based ...

Arduino reads this output voltage of the temperature sensor using Analogue pin A1 and performs calculations to convert this analog value to a digital value representing the current temperature. After ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...
