An Algerian research team has developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a set threshold, boosting efficiency while minimizing water use in ...

DHT11 and DHT22 are two popular sensors among microcontroller users, especially the cheap DHT11s. DHT22s cost more but have better data resolution. My codes are based on MonadnockSystems/pxt-dht11 but ...

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.

Jeppe Djernes Sinding, area sales manager at dol-sensors, recently spoke to The Poultry Site’s Sarah Mikesell at IPPE 2026 in Atlanta, Georgia, USA. Every farm and production system is set up ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Abstract: The design of temperature compensation can create a dependable and consistent working environment for high-precision Application Specific Integrated Circuit (ASIC). This article presents the ...

Abstract: A surface plasmon resonance (SPR) sensor based on a polyvinyl alcohol-graphene oxide (PVA-GO) composite film and a polydimethylsiloxane (PDMS) film was proposed for simultaneous measurement ...

UNSW researchers have developed a thermal-aware tracking algorithm that reduces solar module temperatures and UV exposure during inverter clipping and curtailment, slowing degradation without lowering ...
