It can detect the change in capacitance when a finger is nearby. This means no matter if your finger directly touches the pad or just stays close to the pad, the Grove - Touch Sensor will output HIGH.
You can see the current oxygen concentration from reading the voltage values output proportional to the concentration of oxygen on the oxygen concentration linear characteristic graph. It’s suitabl...
Different from traditional analog light sensor, as Grove - Light Sensor, this digital module features a selectable light spectrum range due to its dual light sensitive diodes: infrared and full spe...
It can detect combustible Carbon Monoxide, Coal Gas and Liquefied Gas. The sensitivity can be adjusted by the potentiometer. Hardware Overview This is an Analog output sensor. It needs to be conn...
The sensor consists of an IR LED and a photo sensor (phototransistor). The light emitted by the IR LED gets reflected by any object placed in front of the sensor and this reflection is detected by ...
