This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in...

There are sevral kinds of Gas Sensor we are providing in Bazzar, if you don't know which one is the right sensor your want, please refer to the tutorial How to choose a gas sensor? Grove-Gas Sensor (O?) is a kind of sensor to test the...

The Grove - HCHO Sensor is a semiconductor VOC gas sensor. Its design is based on WSP2110 whose conductivity changes with the concentration of VOC gas in air. Through the circuit, the conductivity can be converted to output signal that...

The Grove - Speaker is a module consist of power amplification and voice outputs. The loudness can be adjusted by the on-board potentiometer. With different input frequency, the loud-speaker generated different tones. Coding the music...

Grove - Finger-clip Heart Rate Sensor is based on PAH8001EI-2G, a high performance and low power CMOS-process optical sensor with Green LED and DSP integrated serving as a Heart Reate Detection(HRD) sensor.This modual is based on optical...

Grove - Serial Camera Kit includes one control board and two interchangeble lenses, one is standard lens and the other is wide-angle lens. It's a great camera for Arduino centered image recognition projects, because 30W pixel wouldn't be...

Grove - BLE (dual model) v1.0 uses CSR dual mode Bluetooth chip,with the ARM architecture single chip which supports AT instructions, Users can develop flexibly according to the serial baud rate, equipment name, pairing password....

The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high frequency signal that received from the microphone, and outputs...

Grove- Piezo Vibration Sensor is suitable for measurements of flexibility, vibration, impact and touch. The module is based on PZT film sensor LDT0-028. When the sensor moves back and forth, a certain voltage will be created by the...

The sensor is designed for indoor air quality testing. The main gas detected is carbon monoxide, alcohol, acetone, thinner, formaldehyde and other slightly toxic gases. It is compatible with 5V and 3.3V power supply. Features: Low power...
