433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors

CNXSoft: This is a guest post by Florian Robert (1technophile) of the OpenMQTTGateway project about using a 433 MHz LoRa transceiver on an ESP32 board for home automation, specifically to talk to 433 MHz sensors Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car. If we want to be specific, we can talk about the different radio frequencies (433 MHz, 915MHz, 868MHz, 315MHz, or 350MHz) and signal modulations OOK, ASK, FSK that we encounter behind the keyword 433MHz.

Sub-$5 Cavli C16QS CAT1.bis cellular IoT module features Qualcomm QCX216 modem

Qualcomm QCX216 LTE IoT modem was announced at the end of last year as one of the first solutions supporting the new CAT1.bis standard enabling smaller, simpler, and cheaper modules with a single antenna design. This chip also integrates a WiFi scanner exclusively used for indoor positioning. Cavli Wireless C16QS CAT1.bis is one of the first cellular IoT modules based on the Qualcomm QCX216, and we now have a clearer idea of what “cheaper” means since the company says it will sell those for less than $5 to OEMs, although that price is likely in very high quantities, possibly 100k+ or one million pieces. Cavli C16QS specifications: Wireless IC – Qualcomm QCX216 with dual-core Cortex-M3 @ 204 MHz, cellular modem-RF Storage – 4 MB Cellular connectivity LTE CAT 1.bis based on 3GPP Release 14 Peak speeds – 10Mbps (DL), 5Mbps (UL) Bands EMEA: B1/B3/B5/B8/B20 North America : B2/B4/B12/B13/B66/B71 Integrated eSIM […]
