Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with ...
BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.
Abstract: A highly sensitive and stable temperature sensor based on a diamond-Ga2O3 Schottky-p-n diode is demonstrated in this work. The forward current exhibits a pronounced temperature dependence, ...
Abstract: Ultrasonic waveguide techniques are most familiar to monitor temperatures in the hostile environments. A single waveguide could be used as multiple sensors. In the present work, a thin strip ...
