Module with a dust sensor PPD42NS. The board is equipped with a Grove cable and communicates via the PWM interface. Seeed Studio 101020012

Resistive soil moisture sensor. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020008

A small module with a temperature sensor (thermistor). As the temperature changes, the resistance of the thermistor changes, which allows the temperature to be measured in the range from -40 to 125 ° C with an accuracy of 1.5 ° C. The module has a connector in accordance with the Grove standard. Seeed studio 101020015

Module with a sound sensor based on an electret microphone and LM358 amplifier. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020023

The module with a TA12-200 current sensor with a measuring range of alternating current up to 5 A. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020027

Module with a slide potentiometer. Depending on the position of the slider, the resistance value (maximum resistance 10kΩ) changes, which translates into the voltage value at the analog output of the module. The module has a connector in accordance with the Grove standard. Seeed studio 101020036

Module with rotary potentiometer. The connector in this module has been moved to the other side of the PCB, which makes it easier to assemble and use this module. The module has a connector in accordance with the Grove standard. Seeed studio 101020048

A volume sensor designed to detect loud ambient sounds. The module uses a microphone and LM2904 amplifier. The output value (analog signal) depends on the volume of the detected sound. In order to eliminate interference, the microphone signal is subjected to double filtering. Seeed studio 101020063
