1x PCA9685 16-Channel 12-bit PWM Servo Driver
Triacs are semiconductor devices (thyristors) that can allow the passage of AC current through a trigger signal in every half cycle of AC current
when module has triggered
Operating temperature: -40 TO +85
such as the DC-LED screen
YF-S401 Water Flow Sensor 0.3-6L/min antenna 1x PCA9685 16-Channel 12-bit PWMWater flow sensor consists of a plastic valve body, a water rotor, and a hall effect sensor when water flows through, the internal rotator will change its speed with different rate of flow and hall effect sensor outputs the corresponding pulse signal. Use with laser cutters or CNC to measure if and how much water is flowing through laser tube or CNC spindle for cooling. Specifications Working Voltage: DC 5V~24V Maximum Working Current: 15mA @ 5V DC
