Projects classed as hobby.
Arduino
Using and Arduino UNO, RS-485 HAT and Nokia LCD display, monitoring the Morningstar Corporation Relay Driver was demonstrated using available libraries in Arduino. Using the Arduino MKR WiFi 1010 and the MKR RS-485 shield the example sketches of ModBusKitchen sink and SSLWiFiClient were modified slightly to extract data from Relay Driver, convert data to readable values and post to web site.

Raspberry Pi
Raspberry Pi small computer used to test cellular communications software. Modules from Sierra Wireless, Quectel, Telit, MultiTech and Simcom tested. Most cellular modules use USB connections. Developed software applied to the EmbeddedTS single board computers for production. Contact me if interested in a cellular module.
Raspberry Pico
The Raspberry Pico is a small low-cost microprocessor with capability to connect to monitoring and communications devices used in remote monitoring. The devices being tested can operate in Arduino, Raspberry micro-python and embedded C programming environments.
Sierra Wireless MP70 and RV55 cellular modem / routers
The Sierra Wireless MP-70 cellular router was used extensively by police, fire, EMS, and transit vehicles and has many advanced features. This unit is still sold and available from Sierra Wireless. I have a small stock of these units sold as salvage from agencies that wanted to upgrade to units with higher capability. The units I have for testing are older models without LTE bands 14 (FirstNet) 66 or 71.
The RV-55 is optimized for solar power installations with lower power requirements. No Wi-Fi on the RV-55 unit.
The MP-70 is available for fixed base installation – $120.00 including antennas, power cables and assistance in setup.
