+--- Thread: More than 3 DHT11 Sensors GPIO connection (/showthread.php?tid=7844)
More than 3 DHT11 Sensors GPIO connection - classiccars - 03-20-2025
KC868-A16v3
I would like to connect more than 3 DHT11 Sensors but can configure only GPIO47,48,38 in the panel
How can I activate GPIO39, GPIO40, GPIO41 ?
Or can I connect more than one DHT11 to a GPIO?

1. now 1 gpio only use for 1 sensor. maybe in future we will update it.
2. now can't use by GPIO39, GPIO40, GPIO41, but i think next update, we can enable to use it.

Is it the same for 868-AIO?
Can only use tp1 or tp2?

KC868-AIO only use by 2 gpios.

You can activate GPIO39, GPIO40, and GPIO41 by checking the firmware settings for any options to enable these pins.

Interesting question! Regarding the DHT11 sensors, you can't connect multiple directly to a single GPIO pin due to signal interference.

KCS v3 next update will support one gpio with multi ds18b20 sensors.

Interesting question! You're right, limited GPIOs are a pain. For the KC868-A16v3, check if multiplexing options exist in the software/firmware to utilize GPIO 39, 40, 41. Alternatively, consider a different sensor like the DHT22 for better accuracy, or explore addressable sensors on a single data line for future projects, a bit like navigating a challenging level in Moto X3M. No, you cannot connect DHT11 to same GPIO
