The collision sensor is here to simplify the process. It’s also omnidirectional, stable, and sensitive. For all Grove users (especially beginners), we provide guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before your use of the product.

The Grove – Coulomb Counter 3.3V to 5V (LTC2941) is based on LTC2941, its operating range is perfectly suited for single-cell Li-Ion batteries. A precision coulomb counter integrates current through a sense resistor between the battery’s positive terminal and the load or charger. This module measures the number of amp-hours has been used, if you use a fully charged battery, you can test the amount of battery you have used, the remaining percentage, just like the remaining battery shown in your phone. Vice versa, if you are changing a battery, you can use this module to monitor the charging process.

Most importantly, this kit has 20 different Grove modules for a never-ending session of creativity! You can use it altogether with Arduino, Raspberry Pi, or micro:bit. Each module comes in a protective plastic packet. Likewise, all modules are placed in a plastic box (kit). As a result, this kit helps to keep safe all of your modules and cables after prototyping. This plastic box kit is designed to be handy so that you can carry all modules wherever you go!

This Grove module can save you clutter to settle up such an IC by integrating the whole operating circuit. It’s designed for precise differential-input amplification. Input the differential signals of your sensor to this module through the male pins, then your Arduino will get a precisely amplified output from the Grove interface. The gain scale factor is selectable. You can get 35 times or 1085 times amplification via a switch on the board

The Grove – Doppler Radar is based on the BGT24LTR11 Silicon Germanium MMIC which is a 24GHz radar transceiver. It is driven by an XMC1302 MCU based on Arm® Cortex®-M0. This comes in a compact package and runs on very low power, providing high-precision measurements. The high frequency of this module allows for high penetration through objects and therefore this module does not need to be exposed outside when deploying, but rather behind an object. This, in turn, is extremely useful in security systems. Also, this is able to operate in harsh weather conditions such as high temperatures, dust, and rain.

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 a given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.

The electrical conductivity sensor (EC sensor) measures the electrical conductivity in a solution which usually used for aquaculture and water quality testing. The Grove – Electrical Conductivity Sensor is specially designed for a low-cost system with a relatively high accuracy which can cover most applications. The Grove connector and BNC probe interface make it easy to use and very suitable for Arduino and Raspberry Pi project. This Kit includes an EC probe and a driver board, and the driver board supports both 3.3V and 5V system.  

EMG detector is a bridge that connects the human body and electrical, the sensor gathers small muscle signal then process with 2th amplify and filter, the output signal can be recognized by Arduino. You can add this signal to your control system. Note: The sensor cannot be used for medical purposes.
