Enclosure & Peripherals

Nectar Monitor’s circuit board fits into a standard Polycase LP-61 project box and includes button and display pin connections so you can quickly and easily assemble your own device or integrate it into a custom automation project.

The optional Nectar Display Hat is designed to easily connect to the Nectar Monitor through the pin header. It includes 3 displays for pH, conductivity, and temperature, as well as status LEDs for the display scale, calibration state, ATC, and device status. It also includes buttons and pads so you can get up and running quickly with the Nectar Monitor.

Wi-Fi Enabled and Feature-Packed

The Nectar Monitor’s open-source firmware is loaded with professional features to make it simple to use right out of the box or customize for your use case.

  • Universal probe compatibility: Use almost any off-the-shelf pH and conductivity probes with two BNC connections.
  • Simple, fast, and open calibration: Nectar Monitor can automatically detect standard buffer solutions for simple, quick calibration. Once set, the calibration persists across reboots.
  • Automatic Temperature Compensation: Toggle automatic temperature compensation for pH and electrical conductivity and ensure that readings are accurate and responsive to environmental changes.
  • Electrical isolation: Nectar Monitor includes electrically isolated pH and EC probe connections, designed so that the probes can be continuously submerged for 24/7 monitoring without excess wear and tear.
  • Wi-Fi Convenience: Simple Wi-Fi setup and configuration through your phone. View and monitor data on your phone or desktop in a browser, or add your own custom integrations like Home Assistant.
