Sensor ELECFREAKS PlanetX PM2.5
· MPN: EF05028
PM2.5 is the particulates in the air with a diameter less than or equal to 2.5 microns. It usually carries heavy metals and microorganisms, and it stays in the air for a long time, which has a great impact on human health and the quality of the atmosphere. The PM2.5 sensor is able to detect the c...
Monk Makes CO2 Sensor for micro:bit
This board, designed for use with the Lets Talk Science Living Space Project, provides a CO2, temperature and Relative Humidity measurements to a BBC micro:bit. This board was designed by MonkMakes Ltd for use...
Sensor ELECFREAKS PlanetX DHT11
· MPN: EF05004
It is sensitive to changes in ambient temperature and humidity and can be used for high-temperature alarms and environmental humidity detection.PlanetX DHT11
PlanetX UV Sensors
The UV sensor is able to measure the total ultraviolet intensity of sunlight. You can use it to sense ozone and pollutants or make fire safety devices.
Soil Moisture Sensor
This Moisture Sensor can be used to detect the moisture of soil or your pet plant's water level, let the plants in your garden reach out for human help. With the Octopus Electronic Bricks interface can very easy to used with the sensor shield V4.0.This sensor uses the two probes to pass current t...
940nm IR Infrared and Receiver LED
A matched pair of 5mm infrared LEDs — one transmitter (clear) and one receiver (black) — operating at 940nm. Use them to build object sensors, colour sensors, line sensors, distance sensors, and custom wheel encoders. Specifications Size – 5mm Lead Length – 37mm Wavelength – 940nm (infrared)...
Waterproof DS18B20 Temperature Probe 1M with XH2.54mm Connector
Digital temperature sensor DS18B20, waterproof case. Working range from -55 to 125 degrees. Resolution 0.5 in range from -10 up to 85 degrees.
PIR Motion Sensor (JST)
This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.This unit works great from 5 to 12V (datasheet shows 12V). You can also install a jumper wire past the 5V re...
Pololu Carrier for MQ Gas Sensors (Bare PCB Only)
This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, power and analog voltage output—that are broken out with a 0.1" spacing, making the board compatible with 0.1" headers and standard breadboards and perfboards. This bo...
Weather-proof Ultrasonic Sensor
