SensorsCompact board built around a high-sensitivity semiconductor smoke sensor, with a wide detection range, fast response, good stability and a long service life
SensorsPCB probe with analogue output that, when connected to an Arduino or another microcontroller, measures the soil moisture percentage, for example in a flower pot
SensorsBased on the Freescale MAG31110 chip, this compact board measures magnetic fields
SensorsImmersed in a liquid it returns a voltage proportional to the level, down to a depth of 48 mm; it runs on 2 to 5 Vdc.
SensorsModule fitted with a reflective infrared sensor (ST188), an LM393 voltage comparator, a sensitivity adjustment trimmer and both analogue and digital outputs
SensorsProximity sensor built around a voltage comparator chip, an infrared transmitter and an infrared receiver, with a trimmer for sensitivity adjustment, analogue and digital outputs and two status LEDs for power and output signal
SensorsSmall module fitted with a sensor able to measure the UV intensity of sunlight, lamps or other sources, with a wavelength between 200 nm and 370 nm
SensorsMotion sensor using a mercury switch
SensorsBuilt around the APDS-9960 RGB and Gesture sensor; fitted with integrated UV and IR blocking filters, four separate diodes sensitive to different directions and an I²C-compatible interface, this small breakout board delivers light and colour measurement, proximity detection and contactless gesture detection at a distance of 10 to 20 cm
SensorsBuilt around the Sensirion SGP30 air quality sensor, this very small breakout board reports the carbon dioxide concentration (telling you how stale the air in a closed room is) and the TVOC (Total Volatile Organic Compounds), that is the concentration in parts per billion of airborne particles
SensorsSet consisting of an interface board and a 20 kg load cell mounted inside a mechanical frame. The board is based on the HX711 chip, a 24-bit analogue-to-digital converter designed to connect the load cell to a microcontroller such as Arduino, Fishino or compatible boards
SensorsMade up of a probe with two metal terminals and a small module based on the LM393 IC, it measures the moisture content of the soil, for example in a flower pot
SensorsBreakout board built around the tiny TMP102 digital temperature sensor
SensorsThis system controls the liquid level in a tank or basin, letting you fill the basin up to the maximum level or empty it down to the minimum level depending on the operating mode selected. It works with both N.C. and N.O. sensors.
Metal detectorsCompact, versatile metal detector, ideal for tracking down hidden treasure and metal objects. Able to detect coins, jewellery and metal bodies down to a depth of 6 cm, it is perfect for treasure hunters and DIY explorers.
SensorsBreakout board that detects UV-C radiation and provides both analogue and I²C Bus information on the radiation intensity.
SensorsReflectance sensor made up of an infrared emitter diode and a phototransistor
SensorsCompact module built around the DHT22 temperature and relative humidity sensor. Its single-wire serial interface makes it easy to use
SensorsThis compact board, combined with two level sensors and a water pump (not included), automatically controls the water level in a tank, cistern, etc
