This LM75 Temperature Sensor Module is specifically designed for the Banana Pi but it can also be used with the Arduino. This module uses the NXP LM75 Temperature IC.
A reed switch is a sensor that closes the circuit in the presence of a magnetic field. Reed sensors can be used in many applications where contactless on/off is required.
The MT8870 based DTMF (Dual Tone Multi-Frequency) decoder module is commonly used to control robots with a mobile phone, it is also used in different kinds of home automation projects where mobile dial pad inp
This soil moisture sensor module is used to detect the moisture of the soil. It measures the volumetric content of water inside the soil and gives us the moisture level as output.
The HMC5883L is a triple-axis magnetometer compass, which uses I2C for communication. This Module consists of an on-board voltage regulator allowing you to power the module with voltages between 3.3V and 6V.
