Seemoto Wireless IoT Sensors & Gateways for Cold Chain Monitoring
Seemoto Sensors
All Seemoto sensors are wireless, battery-powered IoT devices designed to measure temperature, humidity, and other environmental parameters in real time or offline. They communicate securely with any nearby Seemoto gateway, forming flexible and scalable monitoring networks. Each sensor is easy to install, maintenance-free, and compliant with global cold chain regulations. The collected data is transmitted to the Seemoto cloud platform, where it can be accessed via intuitive web and mobile interfaces, or integrated with ERP and quality systems via API.
TS - Temperature Sensor
The TS sensor is Seemoto’s most versatile and widely used wireless temperature monitoring device. Designed for both fixed and mobile applications, it ensures accurate and automated measurements across the entire cold chain — from fridges and freezers to transport vehicles and storage rooms. Fully waterproof and battery-operated, it’s a plug-and-play solution for real-time or offline logging.

Wide measurement range: –40°C to +85°C
IP68 enclosure: Fully waterproof and hermetically sealed
Up to 6 years battery life (non-replaceable)
Internal memory buffer for offline data
Default 5-minute measurement interval (configurable)
COMMERCIAL USE
- Warehouses and cold rooms
- Retail fridges and storage areas
- Pharmaceutical transport containers
- Mobile cold chain equipment monitoring
TS - PT External Probe
The TS-PT sensor expands Seemoto's capabilities to extreme temperature monitoring, using a high-accuracy external PT1000 probe. This design enables monitoring in environments well below –40°C, such as LN2 tanks, ultra-low freezers, and cryogenic storage, while keeping the electronics protected in ambient temperature.
COMMERCIAL USE
- Deep freezer and cryo-storage (–80°C / –196°C)
- Vaccine and biological sample storage
- Laboratory process monitoring
- Long-term validation for medical manufacturing
THS - Temperature & Humidity Sensor
The THS sensor provides dual-parameter monitoring — tracking both temperature and relative humidity with high precision. Ideal for pharmaceutical warehouses, cleanrooms, laboratories, and industrial areas, the THS ensures compliance with humidity-sensitive storage regulations.
COMMERCIAL USE
- Pharmaceutical production and cleanrooms
- Medical and biotech labs
- High-value humidity-sensitive goods
- Storage and warehouse compliance audits
TS-4XPT External Probe with 4-Channel
The TS-4XPT is a multi-channel wireless sensor designed for environments requiring simultaneous monitoring of up to 4 separate temperature points. Each PT1000 probe is independent and customizable, making this sensor ideal for complex freezer arrays, biotech facilities, or temperature validation studies.
COMMERCIAL USE
- Ultra-low freezer racks with multiple chambers
- Blood bank or organ storage rooms
- GMP cleanroom validation setups
- Equipment/process monitoring with multiple points
TS - Wireless Temperature Logger
The TS-Logger is a standalone, wireless temperature sensor designed for shipment and container monitoring where manual control and visual verification are essential. It adds a physical start/stop switch and LED indicator lights to Seemoto's reliable TS sensor base — making it perfect for pharmaceutical and food shipments that require documentation without constant connectivity.
COMMERCIAL USE
- Food logistics with visual handover control
- Low-cost logging with offline syncing via gateway
- Pharmaceutical transport validation
- Last-mile monitoring with manual handling
TDS - Temperature Display Sensor
The TDS sensor combines real-time temperature measurement with a built-in LCD display, making it ideal for staff-visible installations where on-site visual control is needed. It supports full integration with Seemoto’s cloud system and meets regulatory standards.
COMMERCIAL USE
- Pharmacies and hospital storage areas
- GMP - required environments with visual confirmation
- Front-of-house equipment in labs or biotech
- Fridges in distribution centers requiring on-site display
Temperature Logger with Flight Mode
The Flight-Logger is a variant of the TS-Logger that includes a dedicated Flight Mode, enabling full compliance with airline RF regulations. During flight mode, the logger completely disables all wireless communications, while continuing to log data internally. Ideal for international pharmaceutical logistics, it combines precise manual control with robust memory and global regulatory compliance.
COMMERCIAL USE
- Manual-controlled transport with offline capabilities
- Environments requiring strict RF controls (airports, secure labs)
Commercial Use Cases
- Air freight logistics of temperature-sensitive medicines and vaccines
- Cold chain validation in international shipping
Seemoto Gateways
All Seemoto gateways act as sensor access points, creating wireless networks that transmit collected data to the cloud service. The gateways support multi-sensor, multi-location networks and integrate seamlessly with Seemoto’s backend and APIs.
EGW - Ethernet Gateway
The EGW (Ethernet Gateway) is a reliable, fixed-location device that connects Seemoto’s wireless sensor network to the cloud via a wired LAN connection. Designed for indoor use in secure and stable network environments, EGW is ideal for permanent monitoring installations in pharmaceutical warehouses, food production sites, or clean storage areas.
COMMERCIAL USE
- Cold storage monitoring in pharmacies and hospitals
- Food safety logging in bakeries and production kitchens
- Cleanroom gateway for real-time T/RH data
- Multi-sensor indoor deployment in secure networks
DGW - Display Gateway
The DGW (Display Gateway) is a mobile gateway with a built-in display showing up to four live temperatures. It’s optimized for temperature-controlled vehicles, allowing drivers to monitor cargo conditions in real-time. The DGW supports SIM-based GSM connectivity, which makes it fully mobile and self-contained.
COMMERCIAL USE
- Refrigerated food logistics
- Low-cost logging with offline syncing via gateway
- Cold room transport dolly vehicles
- Clean handover operations with on-screen confirmation
WGW - Warehouse Gateway
The WGW (Warehouse Gateway) is designed specifically for indoor warehouse deployment where GSM network is available but Ethernet is not. It provides a large-area wireless coverage zone for multiple sensors across pharma, food, and industrial warehouses.
COMMERCIAL USE
REV - Range Extender
The REV (Range Extender) is a dedicated wireless repeater designed to expand Seemoto sensor network coverage in large or complex environments. It enables sensor communication in difficult layouts — such as long warehouses, cold storage corridors, or vehicle depots — by relaying data from sensors to gateways, especially in locations with radio signal obstruction.
REV operates autonomously and does not require any network or SIM connection — simply plug it in and it bridges the distance between your sensors and gateways.
COMMERCIAL USE
- Long corridors or multi-room cold storage facilities
MTracker - Mobile Tracker
The MTracker is a rugged, waterproof GPS/GSM tracker designed for mobile and off-grid temperature monitoring, location tracking, and anti-theft applications. It features integrated GNSS and GSM antennas, an internal backup battery, and Bluetooth connectivity — enabling seamless fleet tracking and remote temperature logging in trailers, cold dollies, food delivery vans, motorcycles, and even watercraft.
Its IP67-rated casing ensures complete protection against water and dust, making it ideal for use in harsh outdoor and mobile logistics environments.
