The Dragino LAQ4 allows users to measure and send data, reaching ultra-long ranges via a LoRaWAN network. It provides spread spectrum communication and high interference immunity whilst minimizing power consumption. It is a reliable and simple solution for critical air quality monitoring applications, including laboratory and hospital environments and Green Houses.
It runs on a user replaceable 4000mA/h Lithium battery that is expected to last around 7-12 months depending on the environment. It includes an internal memory capable of storing data records with a date/time stamp that can be retrieved via the supplied programming cable (USB-TTL converter will be required and is sold separately).
Alternatively, stored data can be polled from the LAQ4 via downlink commands, meaning data can be retrieved if the server temporarily goes down. The LAQ4 is pre-programmed to send records every 20 minutes, with capability to be customized to suit user needs.
It also has an alarm function, meaning if either sensor deiviates past a programmable setpoint, the device will immediately trigger and uplink with the sensor values and the alarm status that it can be used to trigger and E-mail, SMS or voice alert through Telemetry2U.
The Dragino LAQ4 can be calibrated manually with a push-button, but it can also do a daily auto calibration based on the best air quality readings over the previous 24 hours. This great helps to improve the accuracy. By default, it is set for manual calibration.
