Through it, you can control a circuit of high voltage with low voltage, say 5V on the controller. There is an indicator LED on the board, which will light up when the controlled terminals get closed.

The resistance of a thermistor will increase when the ambient temperature decreases. It’s this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor i...

The sensor(chip) used in the module is designed with Sensirion’s CMOSens® technology. The chip is well calibrated, linearized and compensated for digital output. The typical accuracy of this module...

We've already released the Grove - I2C Hub (4 Port), now comes the 6 port version, the same size, two more connectors, almost half the price! As you may know, the 7 address length I2C bus allows up...

It can detect the change in capacitance when a finger is nearby. This means no matter if your finger directly touches the pad or just stays close to the pad, the Grove - Touch Sensor will output HI...

Different from traditional analog light sensor, as Grove - Light Sensor, this digital module features a selectable light spectrum range due to its dual light sensitive diodes: infrared and full spe...
