The AM2301 measures ambient temperature and humidity at the same time, which makes it an excellent accessory for LED scrolling signs, message signs and smaller displays where you want to show that data in real time. Pharmacies, banks and public institutions often use it for exactly this kind of readout, which is a useful service for passers-by and measurably increases the number who stop in front of the display. The sensor can also be used to monitor the wall's own operating environment, which over the longer term protects the life of the LED modules. It connects to most synchronous and asynchronous control systems with a simple 15–20 minute cable connection, comes with a 1-year warranty, and is available immediately from regional stock.
Temperature and humidity sensor AM2301
The AM2301 sensor takes a combined measurement: it monitors air temperature and humidity at the same time and passes both readings on to the LED control system. This type of sensor is particularly popular on scrolling signs and message signs, where the aim is to show passers-by or customers useful, real-time information alongside the time and date. Pharmacies, banks, municipal buildings and shops often use this function, because it serves both the brand's presence and a practical service to the public. The sensor can also be used to track the wall's own operating environment, if you want to use the temperature reading not only for display but for monitoring as well, so the marketing and operational functions can be combined under one roof.

Why it is popular on scrolling signs and message signs
Displaying temperature and humidity is a classic, well-proven function on outdoor and indoor scrolling signs, because it gives useful information that everyone understands and at the same time makes the content live and varied. A message sign outside a pharmacy, bank or shop that also shows the current temperature and humidity catches passers-by more easily than a static text, and that in turn improves how well a busy location is used. The AM2301 sensor supplies accurate, continuously updated data, which the control system builds automatically into the displayed text or graphic with no manual intervention — no daily refreshing or editing is needed. At a small cost this function significantly increases the usefulness and appeal of the display, especially in places where walk-in traffic matters to the business, since a passer-by who stops for the temperature reading also takes in the rest of the message.
Installation, dual use and reliability
The AM2301 sensor is best installed where it genuinely measures the outside ambient air rather than the wall's own, possibly warmed internal space — unless monitoring the operating temperature is specifically the aim. The sensor's signal can be connected to most control systems with a simple 15–20 minute cable connection, on asynchronous and synchronous solutions alike, and the installing technician does this in the same pass as commissioning the wall. It has two main uses: public data display (showing temperature and humidity in the content), and monitoring the wall's own operating condition — a high internal temperature can shorten the life of the LED modules, so detecting overheating in good time allows preventive intervention. If you want to use both functions at once, it is worth installing two sensors, one outdoors for the public data and one to monitor the space inside the wall; the sensor comes with a 1-year warranty and is available immediately from regional stock, so a failure does not mean waiting on an overseas reorder.
Buying it for an existing or a new project
The AM2301 can be built into the project when ordering a new LED wall, scrolling sign or message sign, and it can equally be fitted as a later addition to a working system, provided the controller supports a temperature and humidity input — we check that during the free site survey or a short technical consultation. Because it is a stock item, the sensor can be procured and fitted quickly, typically within a few days, with no weeks of waiting as with many bespoke imported components. And if a fault arises within the warranty period, we work with modules that can be swapped immediately and with our own service operation, so there is no corresponding with an overseas customer service desk.
Typical applications
Temperature and humidity sensor AM2301 — frequently asked questions
Does it measure temperature and humidity at the same time?
Yes, the AM2301 is a combined sensor that measures both readings and passes them on continuously to the control system, with no manual intervention.
Where should it be installed?
If the aim is public data display, it has to be fitted where it measures the genuine outside air rather than the wall's possibly warmed internal space; this is determined precisely at installation.
Can it be used for display and operational monitoring at once?
Yes, but if you want both functions it is worth installing two separate sensors, because the outdoor and the internal operating temperature can differ by several degrees.
What is the warranty, and where can it be obtained as a spare part?
It has a 1-year warranty and is available immediately from regional stock, so in the event of a failure there is no waiting weeks on an overseas supplier.
Who wires the sensor in, and how long does that take?
Our technician does the wiring, typically in the same pass as installing the wall; it takes 15–20 minutes, with no separate appointment needed.
Why is a temperature readout worth having on a message sign?
Useful, continuously updated data measurably increases how readily passers-by stop in front of the display, while the sensor can also monitor the wall's operating temperature to avoid overheating.
