When multiple sensor tags are placed too close together, the RF signals may interfere with each other, sometimes leading to a shortened read range or difficulty reading the sensor. When sensors are adequately isolated from each other, the number of sensors being read has no negative impact on the quality of the read. As a rule of thumb, we…[Read more]
Eddy, Thanks for the question.
That reader should work for reading temperature, although we have not tested it specifically.
We are happy to discuss the specifics of your application and sample code request by contacting our customer support team HERE.
Mike, Thanks for the question.
You are correct — the 24-digit number is the Electronic Product Code (EPC) of the tag, not the Sensor Code. The Sensor Code (which can indicate moisture) is located in the “Reserved” memory bank of that tag, in (decimal) word address 11. You’ll have to specify that your reader can get the value at that location –…[Read more]
The read range of a sensor is the maximum distance over which a sensor can communicate with the reader. To operate, a sensor must receive at least a minimum amount of power from the reader, as indicated by the orange line in the plot below. If the power received by the sensor is below this threshold, the sensor will not be able to communicate with…[Read more]
- Tag is too far from the reader
- Tag is placed on a surface it was not intended for
- Reader signal is blocked by an object between the reader and the tag
- Reader signal is being reflected off an object or flat surface
- For fixed readers, the cable connecting the reader and antenna is loose
- Reader transmit power is not set to the…
RFMicron started the topic What are the Components of RFMicron’s Sensor Systems? in the forum Frequently Asked Questions (FAQ's) 2 years, 5 months ago
At RFMicron, we build complete sensing systems designed around our sensors. A complete sensor system from RFMicron typically includes a selection of sensors, a reader, software that runs on the reader, and instructions for installation and use.
The number and type of sensors depend on the application and specific use cases. For example,…[Read more]
RFMicron started the topic What Standards and Protocols Do RFMicron Sensor Systems Comply With? Do Our Sensors Support Regular RFID Capabilities? in the forum Frequently Asked Questions (FAQ's) 2 years, 5 months ago
Our sensors use UHF (ultra-high frequency) RFID technology. Like other UHF RFID systems, RFMicron’s systems comply with ISO/IEC 18000-63 and EPCglobal UHF Class 1 Generation 2 standards dealing with radio frequency identification (RFID) for item management. Within these standards, there are different regulations based on geographical regions. A…[Read more]
At present, all of our sensors are passive. They are designed to be extremely power efficient, which allows them to run the sensing circuits using the power harvested from the reader’s RF signal.
However, this means that a reader must be in close proximity at all times and must probe the sensor to take a measurement. For applications that r…[Read more]

What Can Our Sensors Sense?
Our existing sensors can measure temperature and detect the presence of moisture. Our forthcoming RFM5000 Xerxes line will enable passive sensors that can measure electrical quantities like resistance, capacitance, or voltage in addition to temperature. With these sensors, it will be possible to measure physical…[Read more]
Handheld reader communicating with a RFM3250 temperature sensor
Our sensors harvest energy from radio frequency (RF) signals emitted by a reader. The reader, which itself runs on batteries or line voltage, sends commands (using RF signals) to the sensor instructing the sensor to perform some task, such as executing a sense function or reporting…[Read more]
RFMicron started the topic What are the Advantages of Smart Passive Sensing™? in the forum Frequently Asked Questions (FAQ's) 2 years, 5 months ago
Without a battery or a bulky protective covering, our Smart Passive Sensors™ are the smallest sensors available. They can fit into the tightest of spaces. Our sensors can be placed between sheets of plywood, tucked into the paneling of a car, or hidden in a hospital bed where a patient won’t be disturbed by it. Being battery-free greatly red…[Read more]
Smart Passive Sensing™ is a term used to describe RFMicron’s wireless, battery-free sensors. These sensors are “smart” because they are individually addressable and can wirelessly sense physical quantities like temperature and moisture. Since they can operate without a battery, they are “passive”.

Why monitor switchgear equipment?
Switchgear equipment is designed to work with heavy electrical loads ranging from tens to hundreds of kilovolts. Over time, as the equipment wears down due to electrical and age-related stress, the risk of catastrophic failures like partial discharge and arc flash increases. In the event of such a failure, there…[Read more]
