Features :

1. Compatible with Arduino, Raspberry Pi, AVR, PIC, etc.
2. Measures turbidity of water in rivers.
3. Detects and verifies water quality.
4. Digital and analog output;
5.  Able to detect particles that are suspended in water.
6.  Trimpot for sensitivity adjustment.
7.  Ideal monitoring of water turbidity in rivers, streams, lakes, water boxes, catchment and research sites, laboratories, tanks with liquids and etc.
8. Comes with a module and jumpers

Applications

1. Obstacle detection in robotics.
2. Hand detection in hand driers, soap dispensers, faucets, etc.
3. Gesture recognition in one dimension.
4. Widely used in-camera autofocus to enhance the camera performance in low light or fast-moving objects conditions.
5. Used as a proximity sensor in many phones.

Features:

1. Security power function: When the power is turned on, regardless of the throttle stick at any position will not start the motor immediately to prevent personal injury
2. Throttle range calibrated function: to adapt the throttle differences between different strokes, improve the linearity of throttle response
3. programmed project (available throttle stick or card LED parameter settings):
   1. Brake setting: No brake / with brake
   2. Battery Type: Lithium battery / NiMH
   3. Low Voltage Protection Mode: Soft Shutdown / hard off
   4. Low Voltage Protection Threshold: low / medium / high
   5. start mode: Normal / Soft / Super-soft and start
   6. Timing: low / medium / high
   7. Restore factory defaults
4. Comprehensive protection features:
   1. Under-voltage protection: the program set by the user when the battery voltage is below the protection threshold, ESC automatically reduces the output power
   2. Overvoltage Protection: input voltage exceeds the input range are not allowed to start, automatic protection, also issued a hasty “beep” Warning
   3. Overheat protection: built-in temperature detection circuit that automatically reduces the output power ESC temperature is too high
   4. Remote signal loss protection: remote control signal is lost for 1 second to reduce the power, and then have two seconds to turn off without the remote control signal output

Features :

1. Smooth moving
2. Low friction
3. High rigid
4. Long life
5. Economical and easy to maintain.
