A Sensor Module that detects Water.
This is a basic 16 character by 2 line display.
The Sound sensor module is a simple microphone. Based on the power amplifier LM386.
This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal.
This module is based on 2-Coil Latching Relay.
The Grove - Flame Sensor can be used to detect fire source or other light sources of the wavelength in the range of 760nm - 1100 nm.
Grove – MOSFET enables you to control higher voltage project, say 15VDC, with low voltage, say 5V, on microcontroller.
The sensor on Grove - Gesture is PAJ7620U2 that integrates gesture recognition function with general I2C interface into a single chip.
