Good afternoon

Dear Aaron Lee
HelTec Automation

Henry Espinoza greets you, from GYE ECU.

I saw your page and I think you can help me with a student project on the subject of microcontrollers that I am carrying out.

It consists of a Network of 4 wireless sensors via LoRa for gas monitoring using MQ136 sensors.

I have:

4 HELTEC modules (WIFI LoRa 32) 868Mhz
4 MQ136 sensors (SainSmart MQ136 Semiconductor Sensor for Hydrogen Sulfide)
1 HELTEC HT-M01 Mini LoRa Gateway Module

 I need help with the codes and steps to follow to achieve this:
 
how to connect the sensors to each node HELTEC (WIFI LoRa 32) 868Mhz (pins)?

How to display the gas concentration on the OLED?

How to send the data of the 4 nodes to the HELTEC HT-M01 Mini LoRa Gateway?

How to configure the LoRaWAN network (LoRaServer in ChirpStack)?

Grateful for your help. Heltec products with great will keep learning and promoting the brand in Ecuador.
