 Our next step was to connect the battery directly to the ESP32 using a 5V pin as input or the micro cable USB so we could measure the voltage supplied from the ESP32 from the pins 5V and 3V3 as shown in the pictures:

 In the three schematics, the maximum voltage supplied from the ESP32 to the sensors was 2.73 volts, which is also insufficient to power our sensors.
 .73 volts was the best voltage reached when using the battery in all our trials when connecting the battery using the micro cable USB as input and the 5V pin as output.
 To investigate more, we measured the voltage of the Laptop USB port. The voltage was 5.18 volts, even less than the voltage supplied from the battery.

 When connecting the Laptop USB port using a micro cable USB to the ESP32 and measuring the output voltage from the pins 5V and 3V3, we got the voltage required to power the sensors - almost 5 volts,  and 3.3 volts respectively.:

 Using the 9V battery from the ELEGOO kit is insufficient to power our station using the Pololu and the Power Supply Module 1PC. For that reason, we should find another way to power the station. As we had no other
 components to link the battery to the ESP32, we used a Samsung 5V Adapter to power our station directly from electricity.
