CHJ-708 human body sensor module description (open collector output type)
Infrared technology based on automatic control products, high sensitivity, reliability, low voltage mode of operation, suitable for dry battery power supply, widely used in various types of automatic induction electrical equipment.
Features:
1. Automatic induction: people into its sensing range is immediately output (open collector output), people leave the sensor range is automatically delayed output.
2. photosensitive control (optional, factory is not set): can be set to light control, daylight or light when not sensitive.
3. Two trigger methods: (optional, the default can be a continuous trigger mode)
A. Non-repeatable trigger mode (L): that is, after the induction output, the delay time period is over, the output will automatically shut down;
B. Repeatable trigger mode (H): that is, after the induction output, in the delay period, if the body in its sensing range of activities, the output will remain until the person left after the delay (sensor module Each activity of the body will automatically postpone a delay period, and the last time of the event is the starting point for the delay time).
4. With the sensor block time (default setting: no block time): induction module in each induction output, the delay time to an end, you can set up a block time period, during which the sensor does not accept Any induction signal. This function allows the interval between "induced output time" and "block time" to be applied to the interval detection product. This function can effectively suppress various disturbances generated during the load switching process. (This time can be set at zero seconds - tens of seconds).
5. Low voltage mode: DC0.8V-8V.
6. Output mode: open collector output.
7. Small size, easy to install in various types of electrical equipment internal use.
8. Physical and the following diagram slightly different: in kind 3P power line red positive black negative yellow output
Shape and wiring signal:
Technical Parameters:
1. Operating voltage: DC0.8V-8V; 2. Static power consumption: 1.5mA to 0.1mA (different operating voltage power dissipation, the higher the voltage the greater the power consumption);
3. Open collector output: Load current: <500mA (other current values to be customized) 4. Delay time: can be made range of zero seconds - ten minutes;
5. Triggering time: can be made range of zero seconds - tens of seconds (default: no) 6. Trigger mode: L can not be repeated; H can be repeated (default);
7. Sensing range: <140 degrees cone angle, within 7 meters (specifically determined by the selected lens, can also be customized tens of centimeters to 7 meters or less)
8. Operating temperature: -20- +70 degrees;
