DETECT-IT RL78/I1D detector boards kit Kit User Manual
The Smoke sensor works well, although Standby current is a little high at ~84µA @VDD = 3.4V, ~69µA @VDD =
2.7V. It also works over target voltage range of VDD = 2.7V to 3.5V using an E1 emulator, CR123 battery or external
power supply.
Figure Measurement for Smoke detector
Current measurement can be done at J1 and J2 jumpers, using an ampere meter.
The power consumption of each detector board is the sum of VDD current (measured at J1) and VDD_SENSOR current
(measured at J2).
So when you are doing current measurement, you should remove the jumper and place the ampere meter for doing your
measurement.
J1 and J2 should be then be in position for normal operation of the board with battery or with E1 connection (CN02
power). When measuring current at J1 for example, J2 jumper should always be in place, and vice versa.
