Hi, i have been using a raspberry pi based mains powered swimming pool Temp, PH, ORP sensor for years, now I would like to do the same but battery powered one and using LoRa.  
I already have a LoRa gateway.

In order to avoid any drilling or gluing to the pool wall, i think a floating solution would be the best. I have current sensors in the pipe but the downside of this, i can not measure when the poolpump is off.  
Hourly measurement would be needed in the pool to get alert if ORP or PH goes haywire.

Here is the Raspberry HAT i use currently: [https://www.whiteboxes.ch/docs/tentacle/t3/#/?id=introduction](https://www.whiteboxes.ch/docs/tentacle/t3/#/?id=introduction)

I already looked into it, looks like it would be possible with low power consumption arduino and lora shield.

so the components are:

1. an arduino board [Arduino Mega 2560 Rev3 | Arduino Official Store](https://store.arduino.cc/arduino-mega-2560-rev3)
2. pool sensor arduino board [Whitebox T2 for Arduino – Whitebox Labs](https://www.whiteboxes.ch/shop/t2-mini-mk2/)
3. dragino LoRa shield [LoRa Shield - 868MHz](https://www.antratek.com/dragino-lora-shield-868mhz)

i would need help with the software to read the sensors and send it out via LoRa, as i am not a programmer.

Nice project 😀  
I have made another solution, different hardware:

> **[GitHub - askmurphy/Lora-pH-temperature-sensor: Lora pH temperature sensor](https://github.com/askmurphy/Lora-pH-temperature-sensor)**
>
> Lora pH temperature sensor. Contribute to askmurphy/Lora-pH-temperature-sensor development by creating an account on GitHub.

Maybe you can do something with that?
