Wireless Temperature Sensors
Temperature is the single most consequential environmental measurement across commercial operations, and a wireless temperature sensor is the simplest way to watch it continuously. Temperature decides whether pharmaceuticals retain their efficacy, whether food inventory is safe for consumption, whether industrial processes remain within specification, and whether equipment is operating within safe thermal limits. Yet temperature monitoring remains among the most poorly executed compliance requirements in commercial facilities. Manual log sheets introduce transcription errors and coverage gaps, single-sensor placements miss the zone-level variation that causes the costliest failures, and a reading taken after an excursion does nothing to prevent the product loss, regulatory citations and liability exposure that follow.
Swift Sensors offers a family of temperature sensors engineered for the full range of commercial and industrial monitoring demands, from ultra-low deep freeze environments and pharmaceutical cold chain storage to ambient facility monitoring, industrial process equipment and remote assets. Each sensor reports over Bluetooth 5 (BLE5) to a gateway, and the gateway sends the data to the Swift Sensors Cloud Console over ethernet, WiFi or cellular. Together they form a complete wireless temperature monitoring system, with every unit working as a remote temperature sensor you can check from any device. The moment any sensor detects a reading outside its configured range, instant alerts via email, SMS, or phone call reach your designated team so corrective action can be taken before inventory is compromised. NIST Calibration through an ANAB ISO 17025:2017 accredited laboratory, combined with automated compliance reports, delivers the documented, timestamped temperature record that health departments, auditors, insurance carriers and quality programs expect to see.

Remote Temperature Monitoring Over WiFi, Ethernet, or Cellular
A sensor is only as useful as the connection behind it. Many facilities start by searching for a WiFi temperature sensor or a cellular temperature monitor, but the real question underneath is simpler: will the readings reach your team from wherever the equipment sits? Swift Sensors answers that with a two-step design. The sensors communicate over Bluetooth 5 (BLE5), which is what makes push-button pairing and a 6-8 year battery life possible. They do not join your WiFi network one by one. Each sensor reports to a Swift Sensors gateway, and the gateway carries the data to the Swift Sensors Cloud Console over the connection your site already has:
Ethernet
Connect the gateway to your local network. The SG3-1010 gateway can also be powered with active PoE.
WiFi
The SG3-1010-XR gateway supports 2.4 GHz and 5 GHz WiFi, so there is no network cable to run.
Cellular
Add the SG3-CNM-03 Cellular Network Module (LTE) for remote locations and small offices with no IT support or local network, or as a redundant backup to the WiFi or ethernet connection. A cellular data plan is required.
One gateway supports up to 150 sensors within 100 m line of sight (30 m non line of sight), so a single connection can cover a whole kitchen, lab or warehouse zone. Data is encrypted along the way, with 128-bit AES from sensor to gateway and 256-bit AES from gateway to the Console. If the internet connection drops, the gateway stores readings as long as it has power and uploads them when the connection returns, and the Console can alert your team when a gateway or sensor stops reporting. Where facility power is unreliable, the SS-UPS-15-US Mini Backup Power Supply keeps the gateway running through brief outages. The result is remote temperature monitoring that keeps working whether or not your IT team is on site, with every location visible in one Console.

Swift Sensors Wireless Temperature Sensor FAQs
Is a Swift Sensors sensor a WiFi temperature sensor?
Not directly, and that is by design. A WiFi temperature sensor transmits straight to your wireless network, so every sensor needs its own IP address. Swift Sensors temperature sensors talk to a gateway over low-energy Bluetooth 5 (BLE5), and the gateway connects to the Swift Sensors Cloud Console over WiFi, ethernet or cellular. Because no sensor needs an IP address, there is less IT overhead and cost. BLE5 transmission also drains batteries more slowly than WiFi, so batteries last longer (6-8 years on average) and maintenance stays low. You still get what you want from a WiFi sensor: live readings and alerts on any device.
Can a remote temperature sensor work without a local network?
Yes. For remote locations, small offices and sites with no IT support, the SG3-CNM-03 Cellular Network Module connects to the gateway by USB and sends data over LTE, turning the system into a cellular temperature monitor that needs no local network at all. A monthly or annual cellular data plan is required. The module can also serve as a redundant backup to a WiFi or ethernet connection, so alerts keep flowing if the building network goes down.
Is a wireless temperature sensor the same as a wireless temperature transmitter?
The terms overlap. In industrial settings, wireless temperature transmitters convert a sensing element’s signal and send it to a control or monitoring system. Every Swift Sensors temperature sensor does that job: the sensing element takes the reading and a built-in BLE5 radio transmits it to the gateway, at an inspection rate you can set from 1 to 30 minutes (5 minutes by default). The difference is what happens next. The Swift Sensors Cloud Console stores every reading, shows the trend, and sends alerts when a reading goes out of range. The SS3-117 Wireless Universal 2-Channel Thermocouple Adapter extends the system to a wide range of standard thermocouples, new or already deployed, bringing their readings into the Console with the same alerts and reporting.
What does a wireless temperature monitoring system include?
A Swift Sensors system requires at least one gateway, at least one sensor, and a monitoring plan. The sensors take the readings, the gateway sends them to the cloud, and the monitoring plan gives your team the Swift Sensors Cloud Console for real-time analytics, compliance reports and instant alerts via email, SMS, or phone call. NIST Calibration through an ANAB ISO 17025:2017 accredited laboratory is available for sensors that need documented accuracy, and Swift Sensors manages the renewal.
