Grove - Infrared Reflective Sensor v1.2 can be used for detection of proximity and color of objects. The reflective photosensor - RPR-220 used in this module consists of an infrared light emitting diode and a high –sensitivity phototransistor. Light-colored objects directly in front of the sensor will reflect more infrared light as well as generate more current in the phototransistor than an object with dark-colored surfaces, this can be tell from a built-in indicator LED which will turn red with sufficient flow of current. Also, the intensity of the reflective light increases as the object getting closer. You can adjust the potential-meter on the back of the board if you want to detect a specific object (eg. Black line) at a certain distance.

Digital multimeter for measuring current (DC) and voltage (AC and DC) as well as resistance. 9V block battery additionally required

The Digilent PmodALS demonstrates light-to-digital sensing through a single ambient light sensor. Digilent Engineers designed this Pmod around Texas Instrument's ADC081S021 analog-to-digital converter and Vishay Semiconductor's TEMT6000X01.

3-Axis Compass module, a member of grove family uses I²C based Honeywell HMC5883L digital compass. This ASIC is equipped with high resolution HMC118X magneto-resistive sensors and a 12-bit ADC. It provides compass heading accuracy up to 1° to 2°. Signal conditioning like amplification, automatic degaussing strap drivers and offset cancellation are inbuilt. This grove module also includes a MIC5205-3.3 for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.

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.

A general purpose LED module in Grove form factor, available in different colors. The ingenious PCB design enables you to bend the LED to any position you want, which makes it easy to use it standalone, horizontal or Panel Mount(from left to right in below pics)

Key Specification:

• Standard Grove connector
• Operate voltage: 3.3v/5v
• Emitting Color: Blue

This new version of button twig contains one independent button, which are configured with pull-down resistor ? Ready for use with our microcontrollers as digital input. The button signals the SIG wire,NC is not used on this twig.

What does “P” mean? “P” is for “panel mount” in this product. This Grove – Button is a sister version of original Grove - Button. They are identical except the Grove connecter is moved to the back so that you can easily use it as a neat and wire-free human interface device.

This is a simple yet enjoyable twig to use. The piezo can be connected to digital outputs, and will emit a tone when the output is high. Alternatively it can be connected to an analog pulse-width modulation output to generate various tones and effects.

Sensor is to create Digital (Lo Pulse) output to Particulate Matters (PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust in clean room.
