Oct 28, 2016· WiFi is a power hungry technology. You can expect hundreds of mA while transmitting, and doing that once a minute for, say, 10 seconds (reconnecting to the WiFi takes time) will give you quite a high average power consumption just from the WiFi. The NodeMCU is far from optimised WRT power consumption.
coverage than BLE and 433 MHz, the power consumption restrains it from being implemented into IoT sensor devices. In previous paper [18], we have developed a low-cost WiFi inbuilt device capable of providing much less power consumption than 433 MHz. Later, the same device was modified with a low power MSP430 to further reduce the …
