The MultiSensor family provides a very low cost solution for the need to monitor, measure, record and alarm, remote parameters. MultiSensors are not designed for high degrees of accuracy, but are intended more as relative indicators of the conditions they monitor. The enclosures are not weather proof; they are intended for indoor use and to protect the electronics from coming in contact with external items that might cause failure or damage. With the exception of
MS-T, all MultiSensor products measure temperature and one additional parameter.
In addition to temperature measurement, the MS-TL can provide a general indication of light level. The maximum value of 5 volts corresponds to the light intensity of a 100-watt light bulb at a distance of 6 inches, while a zero volt reading indicates total darkness. To the amount that Vcc falls below +5 volts, the absolute maximum light level will become ambiguous. Most often this is not a concern since the device is intended to indicate light present, or no light present.
Note: There is a hole in the top of the enclosure that is directly over the light sensor. Care should be taken to keep this opening clear and facing the light source to be monitored.
