Nursery Sentry is a wireless IoT solution that provides monitoring and automation for nurseries, greenhouses, orchards, and other agricultural growing facilities. Features include: * Measurement and reporting of temperature, humidity, water depth, soil moisture, wind speed and direction, location, and other variables. * Monitoring of locations without running data or power cables (in some conditions up to 5km away). * A simple mobile-friendly web portal that allows staff to instantly see conditions across the facility. * A flexible rules engine that can send email and text messages when conditions exceed defined ranges. * Rules-based automation for measured conditions: for example, open a greenhouse window if the temperature is too high, or turn on a heater if the temperature is too low. * Detection and alerts of power outages and similar events that might impact operations.
