RAK833 meets Raspberry Pi

You might have heard about The Things Network (TTN from now on) here or somewhere else. If you have not, then it’s a good opportunity to visit the project and check if there is a community of users around you. I have been a core member of the TTN Catalunya community for over 2 years now. This year we are working hard deploying several new gateways in Barcelona and doing workshops and hackathons with the main goal of helping individuals and social entities to carry out projects around a LoRaWan open, libre (free as in freedom) and neutral telemetry network....

Itead Studio Sonoff SC Revisited

A few months ago I wrote about the Sonoff SC sensor hub by Itead Studio. It’s a device with a Sharp GP2Y1010AU0F [Aliexpress] dust sensor, a DHT11 humidity and temperature sensor, an LDR as light sensor and a mic. The sensors are driven by an ATMega328P microcontroller but there is also an ESP8266 on board for WiFi communication, a pretty standard set up when you have several sensors and the ESP8266 GPIOs are just not enough....

Grid-eye camera (sliced, of course)

Tindie is a great place to find uncommon electronic components or weird/interesting boards. I use to stroll around it’s products to basically see what’s new. It’s like Kickstarted but for real. One such uncommon and new electronic components is the Panasonic’s Grid_EYE AMG88 [datasheet, pdf] infrared sensor. And I first learn about it through Peasky Products breakout board at Tindie. And if you have been reading me lately you might know I’m going through my own LED fever....

Sonoff SC with MQTT and Domoticz support

Last December Itead Studio updated their Home Automation product line with a new and different product. The main difference is that it doesn’t have a relay and it’s mainly sensors and no actuator (if we don’t define a notifying LED as an actuator). The Sonoff SC is a sensor station that packs a DHT11 temperature and humidity sensor, a GM55 LDR, an electret microphone with an amplifier circuit and a Sharp GP2Y1010AU0F [Aliexpress] dust sensor in a fancy case that looks like it was originally meant for a speaker....
