BME280 Sensor Module Features The BME280 sensor module is a high-accuracy module for measuring temperature, humidity and atmospheric pressure. The key features are:Temperature Measuring range: -40 to +80 degrees Celsius; Accuracy: 1 degree Celsius In the range of 0 to +65 and 1.5 degrees Celsius out of this rangehumidity: 0-100%RH; Accuracy: 3%RH.pressure: 330hPa to 1100hPa. Accuracy: 1hPaThis module also calculates altitude indirectly using atmospheric pressure. The communication protocol of this sens...

HW-M10 Microwave Sensor Module Features The HW-M10 microwave sensor module is very accurate and widely used for motion detection in alarm and security systems. This module, like the PIR module, can detect any movement. The only difference is that instead of using radiation emitted by or reflected from objects, it uses microwave Doppler radar technology. This module has a digital output that is normally Low and becomes High (3.3V) if it detects motion and remains High for 2 to 3 seconds. ...

MPR121 Capacitive Touch Sensor Features The MPR121 capacitive touch sensor module is a high-precision touch sensor. This module has 12 touch buttons and supports I2C communication and can be easily interfaced with any microcontroller. There is no regulator on the board, so the supply voltage should be between 1.7 to 3.6VDC. MPR121 Capacitive Touch Sensor Pinout This module has 18 pins:6 Pins on the left:VCC: Module power supply – 3.3VIRQ: Interrupt outputSCL: Se...

EMG Muscular Signal Sensor Features In medical research, measuring the activity, contraction and expansion of muscles is important. The EMG muscle sensor measures the muscle activity and produces a signal to show the amount of expansion and contraction. Therefore, the output depends on the amount of activity in the selected muscle. 3 Green, red and yellow electrodes connect to the module for transmitting electrical signals from the muscle motion. Features: Small Form Factor Specially Designed for Micr...

TCRT5000 IR Sensor Features This sensor which is mostly used for line tracking, works like motion detection sensors. It is based on TCRT5000 IC. The TCRT5000 is a sensor that emits infrared light continuously. If the transmitted wave is not reflected or is reflected very poorly, the output will be LOW. If you put an object in front of this sensor, the output becomes HIGH. Note Black color absorbs the transmitted IR radiation and reflects it very poorly. So the output will be LOW if there is ...
