Inspired by the recent pandemic, our project focuses on helping the user wash their hands effectively by sensing temperature and water use. An ultrasonic sensor detects motion and triggers a temperature and water flow sensor to track live data. On ThingSpeak.com, live feeds of the temperature and water flow are graphically displayed while you wash your hands.
The ultrasonic sensor detects motion activity in front of the sink. Once triggered, it will send a signal to the particle cloud. Once motion is detected, the Particle cloud will communicate with the other two Argons connected. One argon has a water flow sensor, while the other has a temperature sensor. Once the ultrasonic sensor is triggered, it will communicate with the other sensors to publish live data to ThingSpeak.
Digital Temperature Sensor
The temperature sensor will be positioned near the outlet of the sink faucet. It’s purpose is to give feedback on the temperature of the water. As water exits the faucet, the sensor measures the temperature and publishes it to the Particle cloud. The data is sent and displayed to a live feed on ThingSpeak. The user can adjust the faucet to find that perfect temperature. No more cold hands.
Water Flow Sensor
The water flow sensor is connected to the waterline of the sink to track both instantaneous water flow rate and total water volume. Once the water starts moving, a hall effect sensor within the device housing reads a signal from the water flow. Sensor frequency is then converted to liters per minute (LPM), and total cumulative water usage (Volume) is calculated. This data is sent to the cloud and is published to a live feed on ThingSpeak. The user can use this to monitor the amount of water used while washing their hands. (Jet ski)
