How long can an ESP8266 run on battery?
For example, an ESP8266 chip with a standard 2500mAh LiPo battery would last for about 30 hours.
How do you power a ESP8266 battery?
With a 9V block battery, you can use the VIN pin of the ESP8266 NodeMCU, that is internal connected with the 3.3V AMS1117 voltage regulator and therefore you need no external components….9V Alkaline Block Battery for ESP8266.

How do you power a PIR?
The PIR acts as a digital output so all you need to do is listen for the pin to flip high (detected) or low (not detected). Its likely that you’ll want reriggering, so be sure to put the jumper in the H position! Power the PIR with 5V and connect ground to ground. Then connect the output to a digital pin.
How do I power up NodeMCU?
Power to the ESP8266 NodeMCU is supplied via the on-board MicroB USB connector. Alternatively, if you have a regulated 5V voltage source, the VIN pin can be used to directly supply the ESP8266 and its peripherals.
How do I power a NodeMCU battery?
The output from the Voltage regulator is connected to the Vin pin of NodeMCU & GND is connected to GND. Hence you can power up the module using 9V/12V DC Adapter or by 9V Battery. On the other hand, if you don’t want to power up the NodeMCU using DC Adapter, you can use 3.7V Lithium-Ion or Lithium Polymer Battery.
Does ESP8266 have voltage regulator?
Powering ESP 8266 You can use LM117 3.3V voltage regulator. The ESP8266’s maximum voltage is 3.6V, so the thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC.

Do sensor lights use a lot of electricity?
Typically, motion sensors use about 1 watt of energy during the standby mode (24 hours a day) and about 5 watts on active mode (an hour a day). Depending on the model, the motion sensor’s power consumption ranges between 0.5W to 8W. By using them you can reduce electricity for lighting up to 70\%.
