Table of Contents
Brainstorming page for GSM Solar Gateways.
- 5V 2W Solar Panel
- MCP73871 MPP Charger - Datasheet
- Needs to be configured for MPP of selected panel
- Battery Temperature Monitoring should be fitted (mainly for low temperature concern)
- LiPo Battery
- ATMega328P
- RFM69HW
- SIM900
Objective
To Provide a Fit-And-Forget UKHASnet gateway for installation on remote structures.
Self Telemetry
- Battery Voltage
maybe:
- Battery Temperature with ds18b20 (so as not to accidentally interfere with the charger thermistor)
Physical
- Waterproof box to be fitted to a vertical pole.
- Solar panel slanted at 45 degrees towards the South (mounted on top?)
- Internal GSM Antenna (chip or window-mount stuck to inside)
- 868 MHz Dipole antenna out through large cable grommet on underside.
