In this tutorial, we will learn about the KY-026 infrared flame sensor module and how to interface it with a PIC microcontroller. We will also see how to use it for fire detection. By the end of this article, you will be able to learn about the introduction of the flame sensor, its ...
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...
In this article, I will show you how to use a force sensor with an ESP32 microcontroller. The force sensor commonly available varies its resistance based on the force applied. You can think of a force sensor as similar to a light sensor. As the light sensor is sensitive to the level of...
In this tutorial we learn how to interface DHT11 and DHT22 Humidity and Temperature sensor with ARM Cortex-M3 LPC1768 microcontroller. I had discussed basics of DHT11/DHT22 interfacing in my previous tutorial. Please go through it if you are new to DHTxx Humidity and Temperature sensors. A ...
Light Intensity Measurement with Pic Microcontroller Automatic Street Light Control Dark Detection Circuit BH1750 Schematic As we mentioned earlier, BH1750 ambient light sensor can be interfaced with Arduino through I2C bus pins such as SDA and SCL that are A4 and A5 pins of Arduino Uno. This sc...
A sensor is an essential device that responds to some environmental variable and converts it into electrical output. This signal may then need to be conditioned, which is filtered, amplified, attenuated, and converted to allow the microcontroller unit (MCU)to receive the input in a usable form...
In this project temperature sensors are interfaced with microcontroller that is connected to a PC.Temperature sensorsconnected are interfaced to microcontroller with the help of analog to digital converter. As, the signal generated from sensors is analog, so these analog signals are converted into di...
The MAX30100 is aPulse Oximetryand heart rate monitor sensor solution. It combines twoLEDs, aphotodetector,optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals. You can use this sensor with any microcontroller like Arduino, ESP8266, orESP32and ...
A0, A1, A2:are address pins of RTC DB1307 chip, which can be used to communicate with the master device. We can control eight devices with RTC interfacing with8051 microcontrollerby A0, A1, A2 bits using I2C protocol. VCC and GND:VCC and GND are power supply and ground pins respectively...
