Description
The sensor can detect temperature of local airspace. The device is suitable for ceiling or wall mount applications. Place the sensor in a suitable location where local temperature should be detected.
The sensitivity can be adjusted with a simple jumper position. This selection changes the gain of an analog amplifier. Choose a gain suitable for typical temperature range. A high gain will detect lower levels. Whereas a lower gain will minimize noise in the signal.
The output mode can be changed from a continuously varying analog signal to a digital signal. The digital signal is produced by a comparator with a threshold at half scale (i.e. 5V) or quarter scale (i.e. 2.5V). Use the analog mode to continuously monitor levels. Or use the digital mode to trigger actuators at a specific event threshold.
Changing the sensitivity and choosing the digital output scale can adjust the event threshold. Setting sensitivity high and digital scale low will reduce the event threshold to a minimum and detect the smallest changes in levels. Whereas, setting sensitivity low and digital scale high will increase the threshold to a maximum and detect only the largest changes in levels.
