Hey, just got this working here, thanks for the write-up! Found the same issue as mark, the BC457 pinout image shown doesn't seem to match the circuit. Switching it around to match the schematic diagram did work however. Cheers!

I'm a little confused,Do you have the schematic?

Hello Rosa, what schematic do you need exactly?

Hi! , oh yeah , about correcting the transistor connection

Hi Dauhee. It's strange. Deep -Sleep is managed directly by the ESP. There is no wiring error?

Apologies, I was incorrect. I cannot upload new code once RST + PIN16 are joined

Didn't work for me. The PIR sensor wakes up the ESP without any reason. I tried changin emitter and connector legs but same.. Any suggestions?

Finally I solved the issue. I'm using Nodemcu and tried the first circuit. The problem was, PIR sensor triggered the Nodemcu rapidly, and forever. I solved this issue by using another one kohm resistor between middle leg of the transistor and the signal leg of the PIR sensor. Thus, the signal strength of PIR sensor is lowered and it doesn't trigger forever. It does only once, when movement is detected.

Thank you very much E-O for your feedback. You went faster than me 🙂

Hi all, When I transferred from breadboard to circuit board I could not get the second schematic (with capacitor) to work at all, it worked on the breadboard okay, then eventually I noticed I had wired the breadboard 'wrongly' but it worked, I realised the resistor to ground was coming off the positive side of the cap in the original breadboard scheme but in fact it should have been coming off the negative side of the cap, when I switched those around on the circuit board it all started working right. Confirmation is also in the last picture. I'm not sure who the author of this piece is but may I say thank you/merci for a rewarding challenge 🙂
