Extremely compact and light weight Digital Temperature Sensor, that use the famous Microchip's TCN75A sensor.
It is capable of reading temperatures from -40°C to +125°C with a precision of 0.0625°C.
This board carries the Allegro's ACS714ELCTR-05B-T hall effect-based ±5A linear current sensor, which offers a low-resistance (~1.2mΩ) current path and electrical isolation up to 2.1kV RMS.
This ambient light sensor carries the TEMT6000 phototransistor, connected to a pull-down resistor to form a voltage divider that produces an analog voltage output between 0V and +5V as a function of the light detected in the visible spectrum.
