Black Body Calibration Sources
-
Nagman Instruments & Electronics Pvt. Ltd
Black body calibration sources by Nagman are used to calibrate infrared temperature devices that are used to measure temperature. Infrared devices can measure extreme temperatures that are very high as well as very low. They allow to measure temperature from a safe distance from the device that is heated or cooled. Calibrating the infrared temperature devices at regular intervals is very important to ensure an accurate and error free measurement. Black body calibration sources allow for an accurate calibration of the temperature devices.

SparkFun Current Sensor Breakout
ACS723 (Low Current)
-
The low current version of the SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for low to moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!
