The DS3231 RTC Module is a low-cost, low-power and extremely accurate I²C Real Time Clock. A Temperature compensated crystal oscillator and Crystal is integrated into the IC itself. It has battery input to maintain the time even the device is not turned ON for months or even years.It is available in many packages for different microcontrollers. We will be...
MQ Gas Sensor use a small heater inside with an electro-chemical sensor. They are sensitive to Gases.Whenever the concentration of gas increases the resistance will decrease (but the current flow will get increased). It leads to change in voltage and it is read at Analog out pin which tells how much gas is concentrated in normal Air. This varied analog...
DHT11 is one of the most used Temperature and Humidity Sensor. It is cheap, compact and provides a reliable data, it is best for a DIY electronics projects.The DHT11 can measure Temperature between 0 to 50° C with ±2 °C accuracy. It can measure Humidity between 20 to 80% with ±5% accuracy. The sampling rate of DHT11 is 1 HZ...
NodeMCU is a popular Wi-Fi based Development board in IoT Projects. Its predecessors are ESP-01, ESP8266-12E. The NodeMCU is based on ESP866 Series.As the name suggests it is a development board, it contains additional circuitry for Power supply USB, Communications, etc (Similar to an Arduino Uno is built around ATMEGA328 IC). Hence this board has built-in voltage regulators to...
Servo motors are widely used in Robots like robot arms and legs. Basically, a servo motor can operate upto 180-degree angle only. It will not rotate full revolution like a DC Motor.A Servo motor can be controlled by degrees like 90 degrees, 180 degrees and 45 degrees. It uses PWM Signals to control the angle of the servo. Hence...

The Raspberry Pi Board has GPIO Pins for connecting it with external devices like LED, HATs, Display, Mic, Sensors, etc.Python is a High-Level Programming Language for General Purpose Programming. The Raspbian Operating System itself included Python along with GPIO packages for getting started. If the...
PIR Sensor is a passive infrared sensor which senses IR (Infrared) emitted by humans (all objects emit a certain amount of IR). A hotter object emits more IR than a colder one.The PIR Sensor is also called as Pyroelectric IR Sensor, Passive Infrared Sensor or IR Motion Sensor. The applications of PIR are Burglar Alarm, Motion detected Floor Lamps,...
