MMA7361 Accelerometer Module Features The MMA7361 is a 3-axis accelerometer with ± 1.5g to ± 6g measuring range. You do not need a library and complex code to use MMA7361 accelerometer. In this module, there is an analog output voltage for each axis acceleration. As a result, you can read and analyze sensor's outputs using an analog-to-digital converter. You can download the datasheet of this module here. [wpdm_package id='17442'] The output voltage for each axis of this module is as follows...

MC-38 Magnetic Sensor Anti Theft Alarm The MC38 is a magnetic switch. When a magnet (the wireless part of the sensor) approaches it, the sensor acts like a switch and the two pins are connected.This sensor is used to detect closed or open doors, windows and alarm systems. Note Magnetic switches are available in two types, Normally Open and Normally Close. In this tutorial we use a Normally Open switch that closes as the magnet approaches the sensor (the two sensor pins are connected). ...
