I have a RPi zero W and am reading four ds18b20 temperature sensors (with a 10K ohm resistor between the data and vcc line). Now and then I keep getting "SensorNotReadyError" from the sensors.
My previous design had one sensor less and didn't have an additional LED and it worked fine. Could it be that the LED + additional sensor consume too much power? I'm using a 2A power brick. Could a 3A solve the problem? Any ideas how to read 4+ sensors with a Rpi zero?
