Heltec Automation Team
Henry Espinoza greets you, from GYE ECU.
I need your help with this:
My proyect consists of a Network of 4 wireless sensors via LoRa for gas monitoring using MQ136 sensors.
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.
