M5Stack® ENV Unit Kit Including 8 Sensor DHT12 Moisture POT PIR HUB Light RGB IR ENV IoT Development Board Switch GROVE

Earth click to buy EARTH unit is a Soil Moisture Sensor for measuring the moisture in soil and similar materials The soil moisture sensor is pretty straight forward to use The two large exposed pads function as probes for the sensor together acting as a variable resistor The higher moisture that is in the soil means the better the conductivity between the two so that the sensor will result in a lower resistance and a higher SIG out You can read the moisture in soil by ADC Inside this Unit we put an extra potentiometers to change the measurement ran ge Angle click to buy Description AN GLE is a rotary switch Unit simply having a 10K potentiometer inside This unit can be used for Continuous singal control such as volume brightness or motor speed A potentiometer is a manually adjustable variable resistor with three terminals Two terminals are connected to a resistive element the third terminal is connected to an adjustable wiper The position of the wiper determines the output voltage The out voltage is captured and converted by AD on ESP32 on portB PIR click to buy Description PIR used to measure infrared IR light radiating from objects in its field of view PIR sensors are commonly called simply PIR or sometimes PID for passive infrared detector The term passive refers to the fact that PIR devices do not radiate energy for detection purposes They work entirely by detecting infrared radiation emitted by or reflected from objects This Unit communica
