This is a hydrogen and nitrogen oxide gas concentration sensor launched by DFRobot. The sensor uses MEMS technology to support gas concentration detection of CO, CH4, C2H5OH, C3H8, C4H10, H2, H2S and NH3. The matching sample code...

F1031V Mass Air Flow Sensor adopts thermodynamic principle to detect flow rate of gas medium in the flow channel, with high precision and good repeatability. It comes with built-in temperature sensor to provide temperature compensation...

Ever want to build your own weather station? This anemometer is made of shell, wind cups and circuit module. It has built-in photovoltaic module, industrial microcomputer processor, and standard current generator. Made with aluminium...

This is an Arduino Carbon Monoxide Sensor. It uses MQ7 probe to detect Carbon Monoxide (CO) concentrations in the air from 20 to 2000ppm. The sensitivity can be adjusted by the potentiometer. The output is proportional to the density of...

This is a waterproofed version of the DS18B20 Temperature sensor . Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it...

what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right！This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through...

This Arduino flame sensor can be used to detect fire or other wavelength at 760 nm ~ 1100 nm light. In the fire-fighting robot game, the flame plays an important role in the probe, which can be used as the robot's eyes to find fire...

As the most basic part of life, air is attracting more and more attention, for example, the most common PM2.5, PM1.0, PM10, etc. Keeping an eye on the quality of the air we breath is becoming quite important. DFRobot brings you this Air...

We all know how do earthquakes occur and what destruction they cause. But as for now, we cannot predict exactly when an earthquake will happen. So the earthquake-resistant design is becoming the new form in most earthquake-prone cities....

The SHTC3 digital humidity sensor from Sensirion builds on the success of the proven SHTC1 sensor and offers consistent high accuracy within the measuring range. The sensor covers a humidity measurement range of 0 to 100%RH and a...

The TMF8801 is a time-of-flight (ToF) distance ranging sensor that uses the time difference between light pulses to measure distance. It provides single zone detection of an object irrespective of the color, reflectivity and texture of...
