How To Add Rain / Snow Sensor To Your Meshtastic Node

Share


On this information, we’ll stroll you thru including a Rain / Snow sensor to your current ESP32 based mostly Lora Meshtastic Node. This information will work additionally for any ESP32-based board like Heltec V3 LoraTTGo, or T-Beam with some modifications.

{Hardware}

Now let’s get began with the {hardware} you want:

🛑

The merchandise is priced at $4.03 however is listed as a delivery payment. Please bear in mind that in case you request a refund, the delivery payment is non-refundable. It is a frequent tactic utilized by AliExpress sellers to keep away from issuing refunds.

📢

When ordering from AliExpress, think about consolidating your purchases from a single vendor to maximise financial savings. As an example, in case you’re buying an antenna from vendor X, test if in addition they provide an IPEX to SMA-Okay cable. By sourcing all of your gadgets from one vendor, you’ll be able to considerably cut back delivery prices.

Meeting

The {hardware} is all prepared and set now to the wiring. For this, we are going to observe the next Schematics.

Rain Raindrops Detection Sensor 3V – Heltec Lora v3

Rain Raindrops Detection Sensor 3V – Heltec Lora v3

Rain Raindrops Detection Sensor 5V – Heltec Lora v3

Rain Raindrops Detection Sensor 5V – Heltec Lora v3
  • VCC -> 3V3 5V
  • DO -> PIN 46 / or Some other empty PIN of your selection
  • GND -> GND

💡

The Rain Raindrops Detection Sensor Module Will Not Work With a Battery, It Works Solely With a USB, in case you determine to make use of 5V for the Heltec Boards

💡

In the event you’re utilizing a special ESP32-based board likeHeltec V3 Lora,TTGo, orT-Beam, merely choose an accessible GPIO pin that accepts digital indicators, helps pull-up or pull-down resistors, and is not already in use. Then, observe the information utilizing the chosen pin, disregarding the precise pin quantity talked about within the directions

💡

Capacitors are good apply for decoupling one a part of a circuit from one other

💡

It is Vital To Be aware That The Order Of The Connections May Range. Comply with The Labels And Io Ports On Your Particular Parts And The Offered Schematics To Guarantee Correct Wiring. Paying Consideration To These Particulars Ensures That You Set up The Right Connections And Keep away from Potential Points or Damaging Your Parts

As soon as all of the wiring is accomplished. Double-check your connections and guarantee they match the recommended structure earlier than continuing to the following steps.

Meshtastic Settings

On the Sensor Machine

  1. Open Meshtastic App (IOS for this information)
  2. Go to the Settings web page
  3. Within the module configuration part go to Detection Sensor
  4. Toggle the swap to allow Allow
  5. Give the sensor a identify
  6. Set GPIO PIN to watch to PIN 46
  7. Lastly, press Save

💡

Detection Set off Excessive is off for this module because it pulls low when rain/snow is detected and excessive on idle. In case you are utilizing a special sensor or your sensor behaves in any other case swap it on

On the Consumer Machine

  1. Open Meshtastic App (IOS for this information)
  2. Go to the Settings web page
  3. Within the module configuration part go to Detection Sensor
  4. Toggle the swap to allow Allow
  5. Proper below the toggle choose Consumer this time.
  6. Lastly, press Save

As soon as that is arrange, you may obtain messages on the general public channel each time the sensor is triggered. It is value noting that in case your sensor is predicted to be triggered ceaselessly, think about setting a restrict within the settings. Saturating the community may probably result in points with sending and receiving knowledge. Take a look at or Channel Utilization publish for extra data

Understanding and Optimizing Channel Utilization in Meshtastic Devices

Channel utilization is the key to efficient communication. Whether you’re engaged in long-range communication, participating in a Helium network, or using other compatible devices like LoRaWAN, monitoring and optimizing channel utilization is crucial for a healthy network.


In conclusion, this complete information ensures seamless integration of a rain / snow sensor into your ESP32 based mostly Lora node or some other ESP32-based board like ESP32 DIY LoraTTGo, or T-Beam Meshtastic Node, extending its capabilities. The directions offered are for Heltec Lora V3, but you may as well apply to some other ESP32-based with minor changes. Keep in mind to be conscious of community utilization to optimize knowledge transmission. This information not solely enhances your system with a rain / snow sensor but in addition opens up prospects for incorporating different sensors. Discover the potential of your Meshtastic Node by experimenting with various sensors and configurations, broadening the scope of purposes to your mesh community. Completely satisfied tinkering and discovering new horizons!
