Changing power source on a PR52-33M

I am using a Wireless Particulate Matter sensor Air Quality / Temperature / Humidity (PR52-33M)
I have sensors installed across the country. When the batteries die it is costly to have them replaced. Is there a way for me to hardwire the sensor using 4v-12v DC? I’m thinking of just removing the batteries and using the red and black wires soldier in barrel plug and then plug in a 12v DC power supply. SEE ATTACHED White Sensor Inside.pdf (70.1 KB)

if you are planning to connect power supply directly to batteries then power supply voltage should not exceed 3.6V.


I was planning to remove batteries completely and just use power supply

correct… but the max inout voltage can not exceed 3.6V.
