Smart Pool Gauge

This wifi-enabled digital pool gauge provides wireless monitoring and instant notification of pressure changes that could lead to pool equipment damage and costly repairs. It will even tell you when its time to clean your filter.

Features

  • SMS and email alerts for 
    • leaks
    • low water levels 
    • blockages 
    • dirty filter
  • Cloud-based web monitoring 
  • No app to install.  Works with any device with a web browser 
  • Runs for 6 months on 2 AA alkaline batteries
  • Pressure Range: 0 - 50 psi
  • Standard 1/4" thread fits most pool filters

Design Features

  • ESP8266 firmware development
  • Schematic design and PCB layout
  • Low power, battery operation
  • PIR motion detection
  • High accuracy, low noise analog pressure sensor
  • 3D CAD enclosure prototyping
  • Amazon IoT and cloud services
  • MQTT interface for home automation

Smart Pool Gauge LC


In response to demand for a lower cost version of the Smart Pool Gauge, we have created this simplified version of the design.  By eliminating the display and associated circuitry we reduce the BOM cost by 40%.  Users can use a T-fitting to continue to use their existing analog gauge while adding remote pressure monitoring at a more affordable price point.

WatFlobot monitors your home's water usage and sends you an alert via email or SMS text message if it detects a leak. No plumbing is required to install WatFlobot and its simple design means it costs a fraction of other leak detectors.

There is no app to install. Instead, just connect to WatFlobot using any device with a web browser (phone, tablet, laptop, etc). Features:

  • E-mail alerts
  • Track your water usage down to the second
  • View water usage history in hourly, daily and monthly summaries
  • No Hub required
  • Support for openHAB (open source home automation software) allows you to extend WatFlobot through advanced actions. For example, alerts can be used to automatically close a shut-off valve, or your Away status can be set via Google Assistant or Amazon Alexa


Design Features

  • ESP8266 firmware development
  • Schematic design and PCB layout
  • High accuracy, low noise audio transducer
  • Sophisticated audio processing on a highly constrained embedded processor
  • 3D CAD enclosure prototyping
  • Amazon IoT and cloud services

Sigfox Board Bringup


In addition to design services we also offer test and validation services.  In this example, we designed the firmware and ran the tests necessary to verify the functionality of this mobile Sigfox tracking unit.  During testing we found a number of hardware issues that we were able to troubleshoot, root cause and provide suggested fixes for. 

Design Features:

  • Low power, battery operated
  • Sigfox long range wireless radio
  • GPS satellite receiver
  • Bluetooth low energy radio
  • STM32 and Nordic Semiconductor chipsets
