The HOBO Light On/Off data logger monitors indoor light changes with an internal sensor.
Using HOBOware®, you can easily configure the logger to record light on and off conditions
making it ideal for building energy audits and light usage analysis. This compact data logger has
a built-in LCD screen for checking status, remaining battery level, and memory consumption.
You can also use the LCD screen to quickly calibrate the logger to the light level in your building
