Features

1). The sensor sensitivity is adjustable. 2). Fillet processing humanized design. 3). Standard XH2.54 interface.

Range of application

Can meet all kinds of resistive sensors (such as photosensitive resistance, thermal resistance, etc.).

Specification

• Operating voltage: 3.3 V to 5 V.
• Output in the form of a: analog output.
• b: digital output, the output threshold.
• Product size: 29.5 mm * 13.5 mm.
• Mounting holes size: Φ 3.

Method of use

1. Probe input interface for two rows of needle, may meet all kinds of resistive sensors (such as photosensitive resistance, thermal resistance, etc.), the internal pull-up 10 k and the partial pressure of the voltage sensor input comparator is end, with the internal regulation of adjustable resistor voltage comparator negative input voltage comparison, the comparison results from OUT output (positive terminal voltage higher than the negative terminal when the output is 1, otherwise 0).
2. Output with SCM any IO port (depending on the process definition) are linked together, through the single chip microcomputer to detect low level changes, thus to detect the brightness of the environment changes.
3. The small plate analog output AO can connect to AD input voltage acquisition.
