1. A system for detecting an amount of R-32 refrigerant in an air temperature controller using an R-32 refrigerant, the system comprising:
an R-32 control board;
a first R-32 sensor electrically coupled to the R-32 control board; and
a second R-32 sensor electrically coupled to the first R-32 sensor;
wherein each of the first R-32 sensor and the second R-32 sensor comprises:
a sensing component configured to detect the amount of R-32 refrigerant;
a bus connector input;
a bus connector output;
a sensor relay electrically disposed between the bus connector input and the bus connector output; and
a sensor feedback port electrically disposed between the sensor relay and the bus connector output;
wherein the first R-32 sensor and the second R-32 sensor are coupled in series to the R-32 control board.
