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 ...

The following image shows the circuit diagram for interfacing the DHT11 sensor module with Arduino. Connections are pretty simple and only require three wires. Connect the VCC and GND of the module to ...

Circuit Diagram The circuit involves the following connections: • DHT11 Sensor: o VCC to 5V on the Arduino. o GND to GND on the Arduino. o DATA to a digital pin (e.g., Pin 2). • An optional pull-up ...

As you can see in the schematic all three TC74 sensors have their SDA and SCL pins connected in series to pin A4 and A5 on the Arduino board. The two 4.7K pull-up resistors must be used when using I2C ...

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 ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Water Temperature Controller – Block Diagram The block diagram of this simple project is shown in Fig. 1 and its circuit diagram is in Fig. 2. The project is built around water temperature sensor ...
