APS Smart Wi-Fi/4G Water Level Sensor & Solar Panel Combo
Two Smart Devices. One Self-Powered Monitoring Solution.
Take the guesswork out of tank management with the Water Level Sensor & Solar Combo. It’s a smart system that monitors your water levels while powering itself from the sun. Combining the APS Smart 4G/Wi-Fi Water Level Sensor with a 3.3W Outdoor Solar Charging Panel, this complete solution also delivers real-time monitoring without relying on mains power. Whether you’re managing a farm, home, remote property, or commercial site, you’ll always know what’s happening inside your tank from virtually anywhere.
Monitor Your Tank from Anywhere with the Sensor & Solar Combo
View live water levels directly from your smartphone or computer using 4G SIM or 2.4GHz Wi-Fi connectivity. The system displays tank level percentage, liquid depth, tank capacity, and status in real time, helping you respond before low levels or overflows become a problem.
Powered by the Sun. Ready Around the Clock.
Forget running power to remote tanks. Instead, the included 3.3W solar charging panel keeps the system operating by charging its replaceable 2600mAh lithium-ion battery throughout the day. Intelligent battery management maintains reliable performance, even when sunlight isn’t available.
Clean, Accurate Monitoring Without Touching the Water
Using advanced non-contact ultrasonic technology, the sensor also measures liquid levels without contacting the water. This helps reduce maintenance, prevents contamination, and provides reliable monitoring for water, fuel, oil, as well as compatible chemical liquids thanks the Water Level Sensor & Solar Combo.
Built for Remote & Outdoor Installations
Designed for demanding environments, both devices feature durable polycarbonate construction and IP67 weather-resistant protection. The system performs reliably in rain, dust, heat, as well as the cold, making it ideal for farms, rural properties, industrial sites, and off-grid installations.
Smart Alerts That Keep You One Step Ahead
Set your own high and low tank level alerts through the app and also receive instant notifications and free email reminders. You’ll know exactly when your tank needs attention, helping prevent unexpected shortages, overflows, and unnecessary site visits.
Designed Around Your Tank
Configure the system to suit your installation with support for multiple tank shapes, adjustable sensor distances, custom measurement units, as well as pump settings. Multi-user access and also support for up to 200 devices make monitoring multiple tanks simple from one app.
