Milesight TS201 Series | LoRaWAN Temperature & Humidity Probe Sensor | EN12830 Cold Chain, IP67

The Milesight TS201 Series is a compact, cost-effective LoRaWAN temperature sensor built for accurate monitoring in harsh and regulated environments. It comes in two variants — the TS201 (temperature-only, DS18B20 probe) and the TS201-TH (temperature + humidity, CMOSens® MEMS probe) — both with a detachable, IP67-rated food-grade stainless-steel probe for field self-calibration.

Certified to EN12830 for cold-chain recording and supporting HACCP workflows, the TS201 measures from −40 °C to +125 °C and runs for up to 10 years on a single replaceable battery. It is configured tool-free via NFC using the Milesight ToolBox app, and supports Milesight D2D gateway-free device-to-device control and FUOTA remote firmware updates — ideal for cold storage, pharmaceutical, food-processing, and industrial monitoring.

Core Capabilities

Dual Probe Variants The TS201 uses a high-accuracy DS18B20 probe; the TS201-TH adds humidity via a CMOSens® MEMS probe. Both measure −40 °C to +125 °C, use a food-grade stainless-steel probe on a 1.5 m cable, and are detachable for self-calibration. EN12830 Certified & IP67 Waterproof Certified to EN12830 for cold-chain temperature recording and HACCP compliance. An IP67-rated enclosure with a specialised battery compartment ensures reliable operation in wet, cold, and harsh storage environments. Up to 10-Year Battery Life A single replaceable 2700 mAh ER14505 Li-SOCl₂ battery delivers up to 10 years of operation (SF7/US915) — around 9 years on EU868 — at a 10-minute reporting interval, minimising maintenance across large deployments. Data Integrity, D2D & Smart Alerts Stores up to 4,000 records locally with automatic retransmission after network recovery. Supports threshold and abrupt-change alarms, Milesight D2D gateway-free device-to-device control, and FUOTA firmware updates.

Industrial Applications

• Cold Chain Logistics & Storage: Monitor temperature from refrigerated warehouses and cold rooms to refrigerated transport, with EN12830-certified recording that satisfies HACCP and food-safety requirements. • Pharmaceutical & Healthcare: Ensure compliant storage for medicines, vaccines, and biological samples in pharmacies, hospitals, and distribution centres, with threshold alarms and full historical traceability. • Food Processing & Industrial Facilities: Use the food-grade stainless-steel probe for direct or indirect food-contact temperature measurement across processing, packaging, and storage areas. • Server Rooms & Climate-Sensitive Spaces (TS201-TH): Use the TH variant to monitor temperature and humidity together in server rooms, archives, and museums that require dual-parameter control.

Technical Integration

Key points for adding the TS201 to your network:

• Connectivity: LoRaWAN® Class A (OTAA/ABP); EU868 (also CN470, US915, AU915, AS923, KR920, IN865, RU864). Milesight D2D enables ultra-low-latency, gateway-free device-to-device control. • Network server: Compatible with The Things Stack, ChirpStack, and AWS IoT Core; FUOTA supports remote firmware updates. • Configuration: Tool-free via NFC tap (Milesight ToolBox app) or LoRaWAN downlink. • Probe & range: Probe on a 1.5 m cable with a 5-pin M12 A-coded connector; the probe measures −40 °C to +125 °C while the device body operates −30 °C to +55 °C. • Mounting: Wall screws, cable tie, or optional magnetic mount; an optional glass-bead thermal buffer bottle stabilises readings in freezers and refrigerators. • Setup help: For deployment planning or integration support, contact the shopioT technical team.

Frequently Asked Questions

What's the difference between the TS201 and TS201-TH?

The TS201 measures temperature only (DS18B20 probe); the TS201-TH measures temperature and humidity (CMOSens® MEMS probe). Choose the TH variant for server rooms, archives, or any site needing humidity too.

What is the measuring range and accuracy?

−40 °C to +125 °C. The TS201 is ±0.5 °C (−10 to 85 °C); the TS201-TH is ±0.2 °C (0–60 °C) with humidity 0–100% RH at ±2% RH.

Is it certified for cold-chain compliance?

Yes. The TS201 is EN12830-certified and supports HACCP requirements through continuous monitoring and reliable, auditable data logging.

How long does the battery last, and is it replaceable?

Up to 10 years (SF7/US915) or around 9 years on EU868, on a single replaceable 2700 mAh ER14505 Li-SOCl₂ battery (10-min interval).

Can the probe go inside a freezer?

Yes — the probe measures down to −40 °C, while the device body operates from −30 °C to +55 °C. An optional glass-bead thermal buffer bottle improves reading stability against door-opening fluctuations.

Does it need a LoRaWAN gateway?

Yes for cloud/server reporting (LoRaWAN Class A; works with standard gateways and network servers). For gateway-free setups, Milesight D2D enables direct device-to-device control. A gateway is sold separately.
