Customer:
I’m reading the instructions for the PIR movement sensor, which states that the sensor needs to warm up for 20 seconds. This implies the sensor draws current during warmup. Do you have a datasheet for this sensor where I can see the expected current consumption during warmup and during operation? My project is battery powered, so this is important to me.

čitam vaša uputstva za korištenje PIR movement sensora; kaže da je potrebno čekati 20 sekundi da se senzor zagrije.
Implikacija je da senzor troši struju – pa me zanima imate li kakav datasheet za taj senzor, gdje mogu viditi kolika mi je očekivana potrošnja tokom zagrijavanja, i kolika je potrošnja za vrijeme rada.
Projekt mi je battery powered, pa mi je to bitno.
Hvala,

Most of the time the board draws 4.35mA, with minor fluctuations when it detects movement. This was measured for the entire PCB across the VCC pin. I think this is a more useful metric than individual components.

veliku većinu vremena sklop vuče 4.35mA, uz manje oscilacije kad detektira pokret. Ovo je izmjeren za cijeli taj PCB preko VCC pin-a. Mislim da je to korisnija metrika nego pojedine komponente. Nadam se da podatak pomaže s projektom
Customer:
What voltage did you use for testing?

Roberte hvala lijepo na odgovoru!
Mogu li samo znati koji napon ste koristili za testiranje?
Hvala,

One more question to be sure: are we talking about the sensor without easyC?
Original message (Croatian)
I jos jedno pitanje samo da budem siguran; govorimo o senzoru bez easyC?
Hvala,

Soldered Support:
Yes, it’s the sensor without easyC. The microcontroller used was an ESP32, so VCC was 3V3.
Original message (Croatian)
da, senzor bez easyC je, a mikroupravljač je bio ESP32 dakle VCC je bio 3V3.
