Electrical parameters LS-2 remote control switch module operating voltage is 4 ~ 6V (DC), typical value is 5V; Operating current is 2 ~ 4mA; Control output terminal (L1, L2) output voltage is4 ~ 6V; Input, output current is 50mA, reflection part of the power consumption is less than 1.5mA; Ip-p reflex drive capability is greater than 50mA; When it is used as a reflection, the reflection distance is 4 ~ 100cm, corresponding external current limiting resistor is 510Ω ~ lkΩ; When it is used as the direct infrared remote control switch, the maximum remote control distance is up to 8m.
Here is the basic application circuit of LS-2.
This circuit remote control distanceis up to 5 ~ 8m
