[Low Power Consumption | Rechargeable] ESP8266 Wireless Switch

Use ESP-12E or ESP-12F master control to transmit signals through the ESP-NOW protocol.

Press the button to wake up the esp8266, and then re-enter the sleep state after sending the signal. The current during the signal sending process is about 100mA, and the sleep current is about 22uA.

(The above data was measured using Hezhou’s IotPower power supply)

The shell is composed of three parts: the bottom shell, the middle frame and the buttons. Just buckle them in sequence, and use the repulsive force of four 10*2mm magnets to pop up the four buttons.

Power consumption after entering deep sleep↑

Current consumption of sending data once↑

The deep sleep power consumption indicated in the esp8266 data sheet is 20uA. I actually measured the total power consumption of 22uA, which shows that the data I measured is relatively accurate.

If the transmission fails when sending data, it will be retransmitted every 200ms. It will go to sleep after the transmission is successful or the retransmission fails 5 times.

The receiving device I am testing here is the curtain motor I am working on. Since there are still some problems with the curtain motor’s shell, I am modifying the shell and will open source it after completion.
