1. Working Voltage: 5 to 18V DC (min tested working voltage 4.5V).
2. Max current draw: 15mA @ 5V.
3. Working Flow Rate: 1 to 30 Liters/Minute.
4. Maximum water pressure: 2.0 MPa.
5. Flow rate pulse characteristics: Frequency (Hz) = 7.5 * Flow rate (L/min).

The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly, and a Hall sensor. It is installed on the water inlet end of the water heater to detect the water flow rate. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The device judges the size of the water flow and regulates it.

1. Severe impact and chemical erosion are strictly prohibited.
2. Throwing or collision is strictly prohibited.
3. The temperature of the medium should not exceed 120 degrees
4. If the water quality is too bad, please add a filter at the water inlet.
5. Do not use beyond the flow range

Orange 8mm NPN Inductive Proximity Sensor RM18 DC6~36V (Unshielded) is a brand new inductive proximity sensor that detects a metal object. Non-flush, or unshielded sensors, do not have the shield around the end of the sensor so the field can radiate from the face to the sides of the sensor in a larger pattern.

This M18 indicates a cylinder type whose diameter is 18mm. The operating voltage range is VDC 6~36V, but the nominal voltage is 30V with detecting distance of 8mm. The sensor has 3 wire and NO (Normally open) type output with RED LED indicator.

The Inductive Proximity Sensor application:

1. Mine metallurgy.
2. Plastics, textile and Chemical Industry.
3. Light industry, tobacco, electric power, railway, and war industry

• As soon as the system is powered, the sensor starts giving output according to the smoke present. It gives the output in the form of a number. 

• We set the threshold for a smoke at 400. So as soon as the sensor gives output higher than 400, the system triggers the condition that smoke is detected.

• Now in this condition, the Arduino board sends the signal to the buzzer to make noise and it will send the signal to light up the red led. 

• As soon as the smoke value falls below the threshold, the condition will be lifted and the Arduino board will send the signal to light up the green led and the buzzer will stop.
