A1QX Telemetry Module Datasheet
Introduction
A1QX is an integrated telemetry module with sensor for industrial applications. Integrated sensors include either temperature, pressure or liquid level sensors which are supplied with the telemetry device. The device and the sensors can either be powered from DC power source or integrated battery with charger for solar panel. Solar panel is optionally delivered as a part of integrated solution.

Question
Specific sensor type will be selected depending on users specific requirements - for example for temperature sensors there are many options from IP68 submersible sensors to high range temperature sensors with different precision options. See our portfolio of H1QT (temperature), H1QP (pressure) and H1QL (liquid level) sensors for full range of options.

Packaging and delivery
Radio modules are packed individually into adequate carton boxes.
Every box contains printed information with technical specification and general business processes information; such as warranty information.
Charging
Some device variations are supplied with integrated rechargeable battery. This battery is either recharged from solar panel (charger is integrated inside radio module) or using external charger.
Danger
Only use approved chargers! Contact info@quorumprecision.com for more information if in doubt.
The battery inside the telemetry unit is charged over the main telemetry units connector. Do not disassemble the unit for charging!
