Test Output Device we used¶
- Solid State Module (SSR-40DA)
- DF Player (MP3 player)
TEST1 : Solid State Module (SSR-40DA) by Hiroe Tadada¶
Mesure the power consumption and standby power for an Solid State Module (SSR-40DA) and the XIAO ESP32C3 board that Hiroe Takeda made on week09.
-
Power consumption of board and SSR (ON):
(NOTE: Power consumption of desk light is not included.)- E = V × I
- 0.31W (0.30752 (E) = 4.96 (v) x 0.062 (A)), in this time
-
Standby power (Power consumption of board (SSR OFF))
- E = V × I
- 0.11W (0.310912 (E) = 4.96 (v) x 0.022 (A)), in this time
TEST2 : DFPlayer (MP3 player) by Shin Masuoka¶
We checked the power consumption of DFPlayer (MP3 player) and the XIAO RP2040 board that Shin Masuoka made on week08.
The result was 1.34W
(Power consumption = board + DFplayer (ON) + speaker)
This device has an amplifier and be able to make sound via speakers. This is why rather high power consumption.
