Hello everyone! I have a question

Camila_99$$•4/12/24, 2:21 PM

I would like to send values from an Arduino to another one (one value every 10 minutes). I have a distance of 80-100m outdoors with trees between the Arduinos. The transmitter should consume as little power as possible because it will be on battery, while the receiver will be on mains power.
What solution do you suggest? I don’t know the maximum distance (WiFi, radio, Bluetooth, IR…).
Thanks

Joseph Ogbonna•4/12/24, 2:23 PM

You can use a simple Lora Device if you are not sure of the distance. It acts as a radio transmitter and covers a large area

wafa_ath•4/12/24, 2:35 PM

hi camila , recommend using LoRa (Long Range) technology, for long-range, low-power wireless communication , you'll need a LoRa transceiver module compatible with Arduino, such as the RFM95W or SX1276/77/78/79 module

InsightMike•4/12/24, 2:40 PM

Another option is Bluetooth with Coded PHY support. This extends the range of bluetooth and is likely the lowest cost and power. LoRa is a good option as well, but your receiver has to function as a gateway. LoRa will have the best range, but BT coded PHY should meet or exceed your range needs as well. As always with wireless range, I would do some field testing with existing product or dev kits before finalizing your design. Also, antenna design/performance is always a large factor with any wireless design.

A few links from today's OH:

Partsbox website or component management: https://partsbox.com/
Compiled list of websites to order part samples(section e): https://docs.google.com/document/d/1Yb828TpndOA_jOLzlhR7l8-WQbaxUj8Vf9b-Ge7XZKk/edit?usp=sharing

And, this is how I see parts management as a maker. At one point, everything gets into one single state proving the quantum entanglement phenomenon.
