A1QX Telemetry Module Datasheet


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.

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.

Order code example

A1QX-P1-R2 ... LoRa 868MHz uplink technology (use with A1QC-R0 LoRa Bridge) powered by integrated battery charged using solar panel.


4-pin Weipu SY1312/S4-N temperature sensor socket

Mating connector on sensor cable: SY1310/P4I-N

pin number function notes cable color
1 GND connected to GND of device internally
2 DQ alt: UART TX
3 VCC alt: UART RX
4 short with pin 1 this pin is connected to - of battery internally

Effectively connecting sensor into port 1 (first port) connects battery minus (-) to GND of the device starting the device.

pin number function notes cable color
1 VCC out (5V) max. 100mA for powering sensor red
2 RS485 - A alt: UART TX blue
3 RS485 - B alt: UART RX gray
4 GND black

7-pin Hirschmann CA6GD sensor connector with wakeup pin

pin number function notes cable color
1 VCC out Battery voltage or stabilized 5V; max. 100mA for powering sensor - either always ON or only during communication red
2 GND black
3 RS485 - A alt: UART TX blue
4 RS485 - B alt: UART RX gray
5 keep not connected
6 WAKE UP SIGNAL A1QX pulls this pin down for 100ms before communication, keeps it grounded for communication, then releases to floating when done. white
7 keep not connected

7-pin Hirschmann CA6GS power connector for solar panel

pin number function notes
1 BATT+ 3.3-3.6V (e.g. LiFePO4 including charging voltage)
2 IO1 charging status of battery (high - charging, low - not charging) (high, low against BATT+ pin)
3 IO2 voltage on solar panel scaled to 0-3.6V max.

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.


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.


Only use approved chargers! Contact 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!
