We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.
Most electronic engineers know that a transistor’s base-emitter voltage (V BE) has a temperature coefficient (TC) of about -2 mV/°C. However, for precision temperature sensors, “about” isn’t good ...
As an important physical parameter that characterizes the state and properties of an object, temperature plays a very important role in our production life. Flexible thin-film temperature sensors, ...
Virtually every modern car on the road is equipped with bells, whistles, and sensors designed to let you know when even the slightest thing is wrong with your vehicle. While any driver can appreciate ...
What’s the difference between a transmitter and a sensor? Nine different types of sensor transmitters. How does each type of transmitter work? What are the components of each transmitter type? Sensors ...
When your car says it’s hot outside, just how accurate is the reading? Where ...
Conventional thermostats are based on separate temperature sensor and heater devices with means for feedback between them. But in some recent EDN design ideas (DIs) we’ve seen thermostat designs that ...
