Capacitive Proximity Sensor (1-10 mm) SF_FPGA The SIM808 with Leonardo mainboard

The SIM808 with Leonardo mainboard is the latest development board for multi-purpose applications

It has an indicator light to feedback the sensor status in real time

so the shields do not interfere with them

the USB-RLY16L is powered solely by the USB bus and provides eight volt free contact relay outputs with a current rating of up to 16Amp each

3V/1A voltage regulator are built-in to the board for power

Capacitive Proximity Sensor (1-10 mm) SF_FPGA The SIM808 with Leonardo mainboardUnlike the inductive proximity switch that can only detect metals, the capacitive proximity sensors can be used to detect all non metallic objects with static electricity besides metal objects. With a power supply range of 10~30V, this capacitive proximity sensor features an adjustable detection range from 1~10mm and an indicator for feeding back device status in real time. Fully enclosed by a PBT plastic shell, the sensor meets IP67 waterproof and
