I will explain how to wire the MIJ-12 preheatless. No PR-01 base is required as it does not require
preheating.

There is a red sticker on the board of [5Vと12V]
[5V&12V]
The PR-01 is a board that supplies the necessary power to the sensor from 4 AA batteries.The PR-01 has
two types of voltage output, [2.5V and 12V] or [5V and 12V], so you can choose according to the sensor.
The instantaneous capacity of each voltage output is 80mA. For general use, the preheat time is 1 second
and the interval is 10-30 minutes. When using AA alkaline batteries, the capacity is 2000mAh, so generally
four AA alkaline batteries can drive the sensor for over a year.
Typical sensor that do not require preheat
