Utra Low Power Wireless Arduino Node
For some time being, I researching a way to have to have a kind of “universal” Arduino node sensor.
When I say universal, I’m talking about connecting to it several sensors like Temperature, Humidity, Lux,… such as LDR, NTC, PTC, DHT11, DHT22, DS18B20, I2C sensors.
At 1st research I tried lot existing, they works fine, but as soon as you want to power them with classic battery (one AAA, CR2032, …) you’re facing other challenges, be able to maximize the battery life and also be able to send wireless frames until battery is reaching it’s end of life.
