Trying to hook up a bunch of them. 7 But when I connect them all I get Null. Too many so I should split on two ESPs or bad connection. The wires on the 1W's are thin....

How many 1W sensors can be used with SigkSens, and ESP8266?

Hello Ranur i would try to set down the pullup resistor on the bus, the many cables will give more capacity. i would try it with half the ohms for beginning. holger (2020-02-11, 09:03 AM)holgerw Wrote:Hi!

So a 2.2 kOh instead of the 4.7 kOh should do the trick you think? //Ranur

Worked as a charm with less pull up resistance. Some trial and error, but mostly due to bad connectors on the D1 Mini. Now it is all ready. 7 1W sensors fitted as well as a Voltage meter hooked up on the analog input. Must be calibrated when properly fitted though. Got some variances now depending on cables and such. Next step - installation! :-D |
