Solar Powered Long lasting 4G GPS Tracker supporting temperature monitoring, RFID, TPMS

Product No.: AT21-4G

It has been designed for challenging conditions such as trailers, containers, boxcars, mining equipments, stationary and remote asset monitoring where permanent DC power supply is not always available. This robust all in one unit offers Solar panel, IP67 rating, large battery capacity, and the added advantage of a solar panel interface. The unit has been rigorously tested on the trailer and remote assets for than 4+ years with the design upgraded several times after the test results gained from real installation.

The solar panel is larger than almost all solar gps trackers on market. It has about 19.1% to 22% sunlight to energy conversion rate to support gps tracker working without vehicle’s battery power supply. But it also supports to be charged by vehicle’s battery. If user don’t change our default settings for data sending interval and sleep mode, device can work always with internal 10000mAh battery and solar power charging.

The MCU is an energy-efficient processor with a very low gate count. It is intended to be used for microcontroller and deeply embedded applications that require an areaoptimized processor. It can keep very low consumption on solar GPS tracker. The scenario which requires the higher power consumption is to send data out to server via 4G module.
• Power consumption uA level
• GD32L233RCT6 chip
• Complete device consumption less than 1 mA in sleep mode
• Working mode standby consumption 25mA
• Peak value 50mA when unit is sending data to server

Several different modes for data sending to save power and reflect device working status.
working mode: normal, sleep, deep sleep, beacon.

Beacon: wake up in fixed time interval.

Normal: no sleep or debug purpose only.

sleep mode and deep sleep mode: same function. It wakes up and sleeps on move/sleep time interval. For sleep mode settings, user can set move interval, go to sleep delay and sleep interval.

User only need to put the solar gps tracking device onto the roof of vehicles or any assets, make sure solar panels exposed to sunlights, then done. User can use our tracking software platform.

waterproof and dustproof plastic case design. PC + ABS plastic material support heat resistant and sunproof design. No matter in what weather conditions, the AT21 solar gps tracking device can work well.

Two 5000mAh batteries packed together to support solar gps tracking. The li-polymer battery can stand with higher than 80°C temperature.

• support for better network connection to other things.
• configurations via bluetooth.

The solar gps tracking device supports 2G, 3G, 4G together. Several types of 4g modules with different bands support guarantee that solar gps tracker can work almost all countries.
Fallback function supported if no 4G or 3G network. It means if no LTE FDD or LTE TDD network, 4G module will fallback to WCDMA network. If failed in searching WCDMA network, it will try to search Edge and GSM/GPRS networks.

• Google map link sent via SMS.
• SMS alert for gps tracking.
• SMS alert for fuel level monitoring.
• SMS alert for tire pressure monitoring.
• configurations via SMS.

With the 4 magnets on bottom of solar gps tracking device, it can be easily attached to metal part of assets like vehicle’s roof. If users don’t need the magnets, these magnets can be removed or replaced with plastic materials.

online tire pressure monitoring. It supports realtime TPMS and history TPMS.

DS18B20 chip temperature sensor connected to solar gps tracking device via 1-wire port. It can detect the temperature -40°C to +125°C. All temperature data would be uploaded to server for realtime monitoring and history record reports. Users can use this temperature monitoring function to detect the temperature of assets or remote areas where no electricity power.

40meters Max wireless distance RFID tags support.
