GY-521 MPU6050 Features The GY-521 is based on the MPU6050 sensor that contains both a 3-Axis Gyroscope and a 3-Axis accelerometer. It uses I2C communication protocol and you can read MPU6050 outputs with SCL and SDA pins. Note The MPU6050 sensor has a digital thermometer in addition to the gyroscope and accelerometer. You can download the datasheet of this module here.[wpdm_package id='18153'] GY-521 MPU6050 Sensor Pinout This sensor has 8 pins:VCC: Mod...

MQ-3 Alcohol Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combination. The MQ-3 sensor is one of the MQ series heater-driven gas sensors that has an internal variable resistance from pin A to pin B, which depends on the amount of alcohol in the air. The sensor's output is an analog resistance. This sensor can measure the alcohol concentration in human blood alcohol gas on your breath. Alcohol decreases the i...

H5V4D RF Receiver Module Features Electronic devices need to be connected wirelessly in so many cases. In these cases, Radio Frequency or RF equipments are often used. RF modules include all radio waves that can travel different distances and reach the receiver according to their frequency and amplitude. This module is only produced at 433MHz. Note All modules that use the 315/433MHz frequency band can communicate with each other and there is no information security in this type of communication. If you ne...

Wirelessly connecting electronic devices is often necessary, and Radio Frequency (RF) equipment serves this purpose.
