Overview
Évitez les catastrophes de plomberie et de fuites d'eau ! .
La carte Click Board™ Water Detect est utilisée pour détecter l'eau et d'autres liquides électroconducteurs. Si la zone de détection est humide, la sortie de l'amplificateur opérationnel CMOS MCP606 de Microchip devient positive, signalant la présence de liquide.
Le Water Detect Click Board™ peut être utilisé comme capteur d'alarme d'inondation domestique, détecteur de pluie pour les bâtiments intelligents ou pour les réservoirs d'eau qui agissent comme un interrupteur de fin de course pour une pompe.

The Water Detect Click Board™ is used for detecting water and other electroconductive liquids. If the detection area is wet the output of Microchip's MCP606 CMOS op-amp will go positive, signaling the presence of liquid.
The Water Detect Click Board™ can be used as a household flood alarm sensor, rain detector for smart buildings or for water tanks that act as a limit switch for a pump.
You could use it on one of our clicker 2 development boards, with GSM 4 click, or any other from the wireless range, and create a home flood alarm. Any time the Water Detect Click Board™ detects water it will send you an SMS.
How Does The Water Detect Click Board™ Work?
The Water Detect Click Board™ works by comparing the voltage of two resistor dividers using the MCP606 comparator. The resistor divider (made of R2 and R3) is used as a voltage reference.
The MCP606 functions as a comparator on this click board™.
The second divider is made of resistor R1 and the sensory area. When the sensory area is dry, it's resistance is near infinite, and the voltage applied to the inverting terminal of the comparator equals VCC.
Since the voltage of the reference divider connected to the non-inverting input is VCC/2, the output of the comparator is at zero voltage. Once the liquid is present at the sensory area, it's resistance drops and pulls the voltage on the inverting input of the comparator toward zero volts. Once this voltage falls below VCC/2, the comparator output swings toward VCC signaling the presence of liquid. The comparator output is tied to the INT pin on the mikroBUS™ header.
The water detection area is actually made of exposed conducting wires - simple but effective technology.
