SEN0463 - Geiger counter issue
ullix 2024-03-03 18:40:31 220 Views1 Replies In the specifications I read: “Signal output: digital output, pull down when a pulse is detected” but in the forum the opposite is confirmed. Which one is it?
The supply voltage is specified as “Supply voltage: 3.3V ~ 5V”. Is the pulse amplitude proportional to the supply voltage, or is it - hopefully - a constant 3.3V?
What is the length of the pulse in micro-seconds? Does it depend on the dead-time of the tube? When I change the tube to some other tube with longer or shorter dead-time, does the pulse length change?

1. Yes, the level of the pulse is VCC.
2. The pulse length I think is uncertain, the greater the radiation the shorter the interval must be. The sensor just outputs a low level when it receives ionizing radiation.
