SDM15 laser distance sensor (DFRobot)
DFRobot SDM15 time-of-flight laser rangefinder: a single measurement point, from 5 cm to 15 m, over UART. To read a distance or spot an obstacle in front of a robot.
Plugs into this board
Piezo vibration sensor (DFRobot)
A flexible piezoelectric strip: the slightest knock, a vibration or a mere touch bends it and makes a voltage. Powered at 5 V, it works as a touch switch or a jolt detector.
Delivery within 2 to 4 business days.
SHT40 Click board (temperature and humidity)
Sensirion SHT40 sensor on a mikroBUS board, I²C. Temperature and relative humidity for an ambient station, at a modest price. Runs on both 3.3 V and 5 V.
Delivery within 2 to 4 business days.
Hall effect Click board
AH1389 magnetic detector on a mikroBUS board, with relay output. Detects a magnet without contact: door opening, shutter position, revolution counting.
Delivery within 2 to 4 business days.
Waterproof DS18B20 temperature probe
Waterproof stainless-steel DS18B20 temperature probe on a one-metre lead. 1-Wire bus: several probes on a single wire, -55 to 125 degrees. For a water heater, a pond or a heating circuit.
Delivery within 2 to 4 business days.
MEMS gas sensor (DFRobot Fermion)
DFRobot Fermion MEMS sensor (MiCS-2714), responsive to NO2, NO and hydrogen. Enough to watch a room's air or track down a leak, on a compact build.
Delivery within 2 to 4 business days.
Capacitive soil moisture sensor (DFRobot)
A capacitive soil moisture probe: no bare electrode to corrode in the dirt, so it lasts. Analog output over 3.3 to 5.5 V, for watering that waits until it is actually needed.
Delivery within 2 to 4 business days.
VEML7700 Click board (ambient light)
Vishay VEML7700 sensor on a mikroBUS board. Ambient light in lux over a wide range, via I²C, with a response close to the human eye.
Delivery within 2 to 4 business days.
DPS422 Click board (pressure and temperature)
Infineon DPS422 sensor on a mikroBUS board. Barometric pressure and temperature over I²C or SPI, with very low power draw for battery builds.
Delivery within 2 to 4 business days.
