Temperature has a significant effect on electronic products. It impacts both the system performance and the expected life of components. With the increasingly dense circuitry in either the same or often smaller packages, the temperature issues can only increase – even with the offsetting impact of increasingly lower power consumption components. Measuring temperature can allow […]
Temperature
What’s the temperature of this thing?
Of course, there are many follow-up questions regarding where or when such as: on just the surface, in the center, on average, instantaneously, or steady state, to name a few. The standard temperature measurement technique that many people first encountered was the mercury (Hg) thermometer to determine if they had a 98.6° or higher temperature. […]
Sensing in Home Monitoring and Control
Joyce Warrington of Ingersoll Rand Residential Solutions explains the sensing that can be incorporated in a home monitoring system at the 2012 International CES (Consumer Electronics Show) in Las Vegas. The control and monitoring is made possible by Nexia Home Intelligence (formerly Schlage LiNK) based on Z-Wave technology. To watch the video, click here. For […]
Infrared Sensor IC Addresses Temperature Measurements in Demanding Environments
Designed to measure high object temperatures (maximum of 1030°C), Melexis MLX90616ESF-HCA thermopile sensors have a stabilization period of less than half a minute instead of times that can extend up to half an hour. In addition to a secondary thermopile sensor that detects temperature variations in the package and in the optical assembly, for integration […]
Sensors Monitor Solar Power Conversion
The conversion of solar energy to electrical power is anything but uniform under varying weather conditions. To monitor several key system parameters, RainWise, a professional grade meteorological equipment manufacturer designed the PVmet Solar Energy Efficiency Monitor specifically for the photovoltaic (PV) industry. The unit can continuously measure key solar panel performance indicators such as ambient […]
A Single-Chip Passive IR Temperature Sensor
Measure Relative Humidity and Temperature Without Wires
Wireless is the must-have attribute for many of today’s consumer and industrial products. When you get two for one, so much the better. With Omega’s UWRH-2 wireless relative humidity transmitter users get both relative humidity and temperature measurements. The battery-powered unit transmits these readings as well as signal strength and battery status back to a […]
Humidity and Temperature Sensor Qualified to Automotive AEC-Q100 Requirements
Many environments require special qualification testing to prove that the product can withstand more than usual application requirements. This can include Underwriters Laboratories (UL), International Electrotechnical Commission (IEC) or in the case of automotive, the Automotive Electronics Council (AEC). Sensirion’s SHT21 humidity and temperature sensor has passed rigorous AEC Q100 qualification testing. The capacitive type […]
Amplifier Targets Precision Thermocouple Measurements
One of the newest signal conditioning circuits addreses the needs of one of the oldest sensing technologies. Designed for K- and J-type thermocouples, Analog Devices’ AD8494, AD8495, AD8496 and AD8497 thermocouple amplifiers include cold junction compensation and a high gain accuracy precision amplifier. The integrated cold junction enables accurate measurements over a wide temperature range. […]
Ease Temperature Concerns: We’ll Call You
Adding to its USB, and Wi-Fi editions, Temperature@lert Cellular Edition monitors the ambient temperature in a server room or other critical area and alerts the user via email, telephone and text message when the temperature rises or falls outside of an acceptable range. The pre-calibrated digital temperature sensor is accurate to within ±0.5°C with a range […]
