The image above shows how the data communication works with the microcontroller and the DHT22. Circuit Diagram for Interfacing DHT22 Sensor with Arduino Now that we have completely understood how a DHT22 Sensor works, we can connect all the required wires to Arduino and write the code to get...
resistance of the sensor changes with intensity of the light and consecutively output voltage also changes. The arduino board can be used along with LDR sensor in order to read the analog voltage. By programming threshold value in the code and reading the realtime values of the voltage from LD...
We will use an Arduino library for the BH1750 light sensor. Go to this link and download the Arduino library. This library is provided by claws on Github. One of the major pros of using this library is that we do not have to worry about the internals of module and configuration settings...
This MOSFET has a low gate threshold voltage of 4 volts and hence is commonly used with microcontrollers like the Arduino for switching high current loads. Here are the main specifications of the IRF520: N-Channel Power MOSFET Continuous Drain Current (ID): 9.2A Drain to Source Breakdown ...
It works within a voltage range of 4.5V to 20V. The Quiescent current is less than 60µA. It has a maximum sensing distance of 3 meters. It provides automatic control along with repeatable triggering by default. The sensor consumes very low power. ...
Interfacing MAX30100 Pulse Oximeter Sensor with Arduino to measure Blood Oxygen & Heart Rate & display SpO2 & BPM on 16x2 LCD Display.
Force Based Sound Generator by Interfacing Force Sensor with Arduino MicrocontrollerStress has become a part of daily routine for millions of people, and if not dealt with correctly, it can cause serious health problems. Stress produces the fight-or-flight response. When it becomes hard to find ...
