Arduino SNMP Voltage Monitor

Project description

using the Arduino with a Wiznet TCP/IP Ethernet chip as a SNMP server to monitor an analog input. The eventual use-case being a battery monitor. Turns out there’s already an SNMP library for the Arduino called Agentuino. It hasn’t been updated in a couple of years, but seems to work well. author modified the code to catch the OID associated with UPS battery charge level (1.3.6.1.4.1.318.1.1.1.2.2.1.0). And just return the value of input A0. This can then be read using snmpget (available in the snmp package on Debian): root@navlaptop:/home/new# snmpget -v 1 -r 1 -c public 192.168.2.64…
