How Rental Companies and Rock Bands Benefit of RF-Enabled Sensors
Nathan runs a company that high-end amplifiers and sound equipment rental for musicians Performers and rock bands. While many of its customers adjust experienced electricians, cobbled together the other equipment and cabling – what equipment to a Overheating may result.
The less experienced tenant may not be aware of voltage drop and cable run boundaries between stage floors. Reduced Voltage at the far end creates high temperatures and internal devices combined with increased ambient temperatures of stage lighting, and cable overheating – Stage technology may be damaged or have its life reduced. Sensitive electronic components wear out faster than expected, Nathan, that is, increased maintenance and replacement costs – Any costs that are passed on to its customers.
Even with careful contract language, as Nathan is able to monitor and review its operating to protect investment or fee when he became the unit overheated knows?
HF RFID-Enabled Sensing
Melexis MLX has created 90 129 sensor IC that can be customized with multiple sensor inputs and read with a 13.56 MHz radio frequency identification (RFID) reader from Proxima RF. With the MLX 90129, a simple, inexpensive temperature data logger could be fixed operating rental equipment checks on rental income with a handheld reader.
The read / write sensor IC includes an internal temperature sensor and three auxiliary inputs for recording and monitoring. The combination of resistive sensing with passive high-frequency (HF) RFID, Melexis sensor opens the door to new applications that previously difficult to achieve. As a bonus, the HF RFID labels unique product can be used for inventory control and rental plus be protected by a password for extra security.
What may be perceived?
The Melexis sensor IC can be used for more than just temperature. In combination with almost any resistive sensor to up to three sensors or monitoring ports, the IC sensor data by proximity to monitor applications that RFID offers:
=> Strain or Force sensors measure small movement, stretching, weight
=> Pressure (air, hydraulic pressure, vacuum)
=> Flow (liquid or gas)
=> Temperature, humidity
=> Voltage, resistance and current
=> Damage, tilting to break a seal
=> Proximity of nearby objects or linear position
=> Shock, speed, angular position, and light
=> Run time, duty cycle, on / off
Battery or Less Sensing Data Logging?
The combined sensor Melexis IC 90 129 and sensors are encased in a number of different form factors, of small, inexpensive plastic housing to water-proof and high temperature systems. The entire sensor can be embedded in equipment or construction of an "in situ" battery pack less product for the opening of sensing data at a given time to create. The low-power sensor IC with passive 13.56 MHz interface supplied with power from the RF reader Proxima RF designs – that is, energy harvesting, designers can embed sensors in products and equipment in which water and liquids are a problem for Ultra High Frequency (UHF) RFID.
By adding a battery, the sensor is a data logger – matched by data points on a schedule required on application.
Why for High Frequency sensors?
HF is a "close reading" that technology has a short read range. Shorter read ranges are useful, where personal, human intervention is preferred or already part of standard operating procedure as in health care, high-security Applications or mission critical or sensitive equipment. Personal interaction allows human review of literacy and the environment, to provide redundancy in the system Add. The short read range ensures 100% read, read without interference or need for anti-collision software as necessary with more active UHF technology used in real time Locate and inventory systems.
High frequency 13.56 MHz RFID has superior performance and properties of fluids in and around it a logical choice for the Use of sensor systems used to monitor food, beverages and liquid products are either in process control, manufacture, transport or storage.
could read the touch of nature of passive RFID 13.56 MHz results in less ambient light emissions – an advantage in medical applications or create an emissions somewhere Problem with sensitive electronic equipment. The recent HIBCC 4.0 ANSI standard specifically recommends the use of HF in the health care concerns that the active UHF may affect sensitive equipment be reduced.
RF reader – desktop or mobile
The sensors can MLX 90 129 with the off-the-shelf RF Proxima Desktop Reader USB or AV-X Mobile Reader. The FCC / CE USB desktop reader has an internal antenna, so requires no additional parts be. The small box polycarbonate draws power from the USB port and includes an LED for visual read receipt.
The Proxima AV RF-X mobile RF reader is specifically Psion Teklogix Workabout for the rough Pro product line. The reader to work with the other radios in the handheld device – the operator can keep the WiFi, Barcode Scanners or GPS running while reading that the HF. Since many mobile users require read, the AV-X is a perfect fit for RF-enabled sensor applications.
Develop Applications for HF RFID-enabled sensors
Melexis RF and Proxima have joined forces to create the 90 129-Kit DVK-sensor, so can Developers to easily evaluate the features on the MLX 90 129 sensor IC. The kit contains an evaluation board with pre-populated a temperature, light sensor and a potentiometer. The evaluation board is read using the USB desktop reader from Proxima HF RF. The kit includes powerful drag and drop dashboard software. An optional key ring style temperature sensor (ST-KF1) can use the kit for developers interested in testing the sensor in an application ready form factor can be ordered.
The DVK 90 129 is available from Future Electronics or your local representative Melexis.
Why Rock Bands Should Care
Nathan, equipment renters, like every Company person, he has to make sure he is a high quality product, protects their investment and keep costs low. If he finds his equipment life by overheating is reduced, it will simply require more. But everyone saves time, money and headaches by reviewing operating immediately with a simple, mobile reader. And rock bands can go back to making music.
