CNX Software ☛ Renesas RRH47000-EVK board integrates RRH47000 CO2 sensor with ±75 ppm accuracy, relative humidity and temperature sensors
Renesas has recently released the RRH47000-EVK evaluation board based on the RRH47000 CO2 sensor using non-dispersive infrared (NDIR) technology to measure CO2 levels accurately (±75 ppm typical) within the 0-5000 ppm range. The sensor also includes built-in sensors for relative humidity and temperature, operates at low power, and supports either UART or I2C interface to the host.

Arduino ☛ It’s silver, it’s green, it’s the Batteryrunner! An Arduino-powered, fully custom, electric car
Indeed, it’s impossible not to notice that the vehicle is made entirely from aluminum: specifically, 5083 aluminum alloy. This material is extremely durable and can be easily recycled, unlike plastics or carbon fiber which end up as waste at the end of their lifecycle.
The car’s bodywork includes thousands of laser-cut aluminum pieces. “This isn’t just a prototype: it’s a real car – one that we’ve already been able to drive across Europe,” Charly says.
