It can be applied to environmental noise testing, such as highway noise monitoring stations, bedroom noise monitoring, etc.

Nowadays, there are many kinds of sounds surrounding, some of which are really noisy. It is really essential to measure whether the sound is noisy enough to do damage to our health.

The sound level meter (also known as the decibel meter, noise meter) is a basic noise measurement instrument. We have launched a sound level meter, which is compatible with Arduino, plug-and-play. It can accurately measure the sound level of the surrounding environment. This product uses an instrument circuit, low noise microphone, which makes it highly precise. It supports 3.3~5.0V wide input voltage, 0.6~2.6V voltage output. The decibel value is linear with the output voltage, which leads to a simple conversion, without a complex algorithm. The connector is plug-and-play, without welding, so this product can be easily used in your application.

Hall Sensor (GD)

Want to measure Hall Effect? We have the Grove – Hall Sensor v1.0 for it. It’s a Grove compatible and continuous-time hall sensor by Seeed Studio especially made to measure Hall Effect. The Hall Effect is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the continuous-time switch Hall Sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turns on when the magnetic field disappears.

The output of the continuous-time switch Hall sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turns on when the magnetic field disappears. This sensor has a 400ns transition period for rise and fall as well as reverse battery protection. It is easy to use and compatible with the Grove interface. You can use it for RPM meter and Simple DC motor.

For all Grove users (especially beginners), Seeed Studio provides guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before your using of the product. This is a suitable product for not only Grove users but also all electronic enthusiasts. So buy it now!

Grove Coulomb Counter 3.3V to 5V (LTC2941) (LTC2941)

The coulomb (symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: Q or q) transported by a constant current of one ampere in one second:1C=1A•1s. A Coulomb Counter is a device to measure the current that your devices or sensors are using.

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.
