    Ultra low power transmitting for short distance

    Hi, I am using a small battery to power both a sensor and a transceiver to send a signal for ~500 meters. I am looking for the lowest power-consuming method. I don't really care about how low my transfer rate. 1 sample per 1 is good enough For my sensor, I was thinking of using a Thermistor...

    LoRa communication with arduino

    I want to set up a communication system with lora module using arduino. The lora module is said to have a high range (<15km), but when I go about 50-100 meters away, my connection drops. Also, when I integrate a sensor into this system, I can't get an output from my sensor. When I try the same...

    How do multiple wireless devices avoid communication collision

    I try learning through youtube and other resources for example WiFi works on 2.4Ghz actually there are other 8 bands too (some other frequencies next/before 2.4Ghz) so different devices use those different bands/frequencies to communicate at same time, for sure on receiving end we have 8...

    I bought these modules from Aliexpress, as we know sometime they are not what we expect. Its RFM96 (or may be RF96 if actually that is different) when i was going through datasheet at end of the datasheet it was clearly said that RF95 family supports 868Mhz & 915Mhz but RF96 supports 433Mhz I...

    How does LoRa work in ESP32

    Hey. I want to try to make low power device based on ESP32 to send readings to the server. I have come across this tutorial that describes how to get lora working on ESP32: https://randomnerdtutorials.com/esp32-lora-sensor-web-server/ Lora reicever function: void getLoRaData() {...
