HC-SR501 is based on infrared technology, an automatic control module with high sensitivity and ultra-low-voltage operating mode, making it highly reliable to use. It is widely used in various auto-sensing electrical equipment, like battery-powered automatic controlled products. Wiring  The HC-SR501 sensor operates at 5V to 20V, and the digital output pin gives out a HIGH or LOW signal depending on if the sensor detects any motions. Thus, the sensor can be used without connecting to a microcontroller and just by a power supply and a load. For instance, it can be connected to the power supply and a lightbulb. Then,...

The DHT11 is a basic, low- humidity and temperature sensor. It makes it really easy to add humidity and temperature data to your electronics projects. It is used for remote weather stations, home environmental control systems, and farm or garden monitoring systems.    In this article, we will be talking about the set up and operating the sensor with an Arduino Board.  The DHT11 sensor has some range and accurate for collecting data:  If you want to know more, check out this DHT11 data sheet.  Humidity Range: 20-90% RH Humidity Accuracy: ±5% RH Temperature Range: 0-50 °C Temperature Accuracy: ±2% °C Operating Voltage:...

The Soil Moisture Sensor Module (Capacitive) acts like a capacitor where the water level changes the capacity and we can measure that charge and discharge timing. It is a popular module for measuring the moistness of soil. The biggest advantage over a traditional moisture sensor is that the capacitive sensor doesn't corrode. In this article, we will talk about how to wire and set up the module for operation with an Arduino Board.  Wiring  Most soil moisture sensor module operates between 3.3V to 5V and produce an analog output. For this project, we will be using Soil Moisture Sensor Module (Capacitive),...

LCD is widely used in applications to show characters and messages other than using the serial monitor. Our LCD shield kit makes it easy for you you to connect a LCD with an Arduino without using up any of the digital I/O pin except for the 2 I2C pins. As a result, you can connect more electronics into one shield, making it much easier to work with on the Arduino boards.  Part List LCD Shield Kit Female to Male Header Pins Arduino Uno R3  Arduino IDE Equipment List Soldering Iron Wire cutter Solder lead-free The LCD Shield Kit comes with the following parts.  Assembly...

The Soil Moisture Sensor Module (Resistance) consists of two probes which are used to measure the volumetric content of water. The two probes allow the current to pass through and then it gets the resistance value to measure the moisture value. However, the major issue with resistive soil moisture sensor is the corrosion of the sensor probes. it is because it is in contact with the soil while there is also a DC current flowing which causes electrolysis of the sensors.  In this article, we will talk about how to wire and set up the module for operation with an...
