Waterproof Temperature Sensor
It measures temperature of water flow in water distribution system from either tank to users or reservoirs to tanks. DS18B20 sensor as shown in below Figure measures temperature of water flowing in water distribution system from either tank to users or reservoirs to tanks. Its color is predominantly black. Material used to build this sensor is durable stainless steel. Cable length is 100 cm. Stainless steel tube size is about 6 * 50mm (diameter * length). Range of power supply is 3.0 V-5.5V. It is an original chip DS18B20, of three wire temperature sensor. There are three Cables: Red (VCC), yellow (information), black (GND).
Humidity and Environment Sensor
DHT11 sensor requires 3.5V to 5.5V DC for operation.
It measures outside temperature in range of 0 to 50o
C using thermistor.
It measures humidity in range of 20-95% using capacitive humidity sensor.
It gives result after at least every 2 seconds.
With the data received from sensor, we are able to study the effect of humidity and outside temperature on corrosion of pipe, actuators and sensors.
