Convert Wireless PIR sensor to use power supply instead of B

[Naynesh]

I want to convert a wireless PIR\Door Sensor so that it runs from a power supply rather then battery's

Currently it take a single or double AA 1.5v Battery

I have multiple PIR's so need some kind of a solution where 1 can use one power supply for all the devices.

Specs are below, Any Advice?

Door Contact
Power supply: DC 1.5V (1 x AA 1.5V LR6 Battery)
Satatic current : ≤30uA
Alarm current : ≤40mA

PIR Sensor
Power supply: 1.5V AA battery x 2
Static current: =< 70uA
Alarm current =< 7mA

I can't find a mains 1.5V supply advertised anywhere. But if you already have a plug adapter that can provide 5VDC or more, you can reduce its output to 1.5V with a buck converter like this one.
