Product Description
The picture is for reference only
Features:
1. The sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment, against oxidative, conductivity, superior performance and longevity;
2. The comparator output, the signal is clean, waveform, driving ability over 15mA;
3. Distribution bit to adjust sensitivity;
4. Operating voltage 3.3V-5V
5. The output in the form: digital switching outputs (0 and 1) and analog AO voltage output;
6. A fixed bolt hole for easy installation
7. Voltage: 5V
8. Power indicator, the output signal LED indicator.
9. TTL-level output, TTL output valid signal is low. Driving capability 100MA so, can directly drive relays, buzzer, a small fan, and so on.
10. Sensitivity can be adjusted via potentiometer
