Gravity: Geiger Counter - module with Geiger counter

Module with a light intensity sensor BH1750FVI dedicated to the M5StickC sets. It communicates via the I2C interface. M5Stack U134

A compact pressure and temperature module ideal for weather stations, drones, and IoT projects. It offers a measurement range of 300–1100 hPa with ±3 Pa accuracy and temperature measurement with ±1°C precision. With a built-in 3.3V regulator and logic level converter, it works with both 3V and 5V microcontrollers. STEMMA QT/Qwiic connectors make it easy to quickly connect and daisy-chain multiple sensors in a single system. Adafruit 6420

Module with 7 QTR type optocoupler with analog output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 40 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4207

The module allows you to attach a strain gauge (working in the Wheatstone bridge circuit) and convert the analog signal into its digital representation, available on the module output lines. The system processes the signal with a 24-bit resolution and can be powered by 2.7V - 5.5V. The module is especially recommended for constructing digital scales in combination with Arduino

Crowtail – Flame Sensor 2.0 is a module detecting infrared radiation and flame sources, operating in the range of 760–1100 nm. Intended for use in safety systems, robotics, and educational projects.

Module with a light intensity sensor BH1750. The measuring range is from 1 to 65535 lux, and communication is carried out using the I2C bus. Adafruit 4681

The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5258

Module with pressure, temperature and humidity sensor BME280. It allows to read the atmospheric pressure in the range from 300 to 1100 hPa and communicates via the I2C or SPI interface. Waveshare BME280 Environmental Sensor

A moisture sensor specially adapted to work with the Kitronik Greenhouse Kit for the BBC micro:bit. It allows monitoring of moisture in the soil. It can be programmed using any editor for the micro:bit. Kitronik 56107

The Pololu MinIMU-9 v5 is an inertial measurement unit (IMU) that packs an LSM6DS33 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny 0.8″ × 0.5″ board.

Motion detection module featuring Panasonic\'s EKM series PIR sensor. The EKM series is optimised for detecting small movements and is ideal for detecting movement in a small area around the sensor. It offers digital output in 32 zones with a detection distance of 5 m and a detection area of 90° x 90°. SparkFun SEN-22000
