Hi all,
Thanks for all the help. These are my further actions:
- I'll increase the size of the power traces
- Add GND plane and wires between sensor wires
- Include connectors for capacitors. When the PCB arrrives, ill measure the power at the end of the traces and then decide wether the...
The 56kHz signal drives the LEDS, these traces are seperated by at least 2.5mm. The sensorOUT wires are seperated by 1mm (5V, low amp).
I could not test anything because i did not order the pcb. I wanted to ask these questions before spending a lot of money which i dont really have. I did...
LED driver: 5V - 80 mA (4 parallel series: I supply per series: 20mA) on PCB this is 'powerb.'
Sensor driver: 5V - 7mA (10 parallel units: I supply per Unit: 0.7mA)
Sensor output (High): 5V - 0.5mA (not sure, could not find on datasheet) (these are the BLUE wires on SZ-001a.pdf)
Sensor output...
I will bend te sensors so they line up with the leds and face the same direction.
I plan to have the PCB made by a service, it breaking in transport is a valid point, i will look into that.
thought about making modules but was worried more connectors might mess up the PMW signal or te sensor...
Appologies,
tssp40.pdf is sensor datasheet.
Indeed, each sensor is paired with a LED, 6ish feet away.
Sensor and LED are not narrow beam, however, the sensors are only able to see one LED through a small hole in the casing.
I tested this and it works.
Hi all, first post, don’t know if correct topic,
For these kinds of questions, I would have usually asked a professor of mine but Corona is a bummer and he is not able to respond, your help would be greatly appreciated. I am quite a novice in electronics design and finally mustered up the...
