TI’s TMP007 is an IR Thermopile sensor which measures the temperature of an object without contacting the object. Board designed as a Teensy 3.x add-on where power and ground are provided by digitalWrite(HIGH/LOW) from Teensy GPIO pins due to very low-current (270 microAmps) operation. Interesting design challenge since the sensor is very sensitive to thermal noise so pains have to be taken to thermally isolate the tiny BGA sensor. Sensor has an alert (interrupt) function as well as one of the two address pins broken out here so two of these can be on the same I2C bus.
