SenseCAP T2000-A vs T2000-B vs T2000-C: Which One Do You Need?

26th October 2026•By Neil Skoglund

T2000 Guide

The three SenseCAP T2000 trackers look almost identical. They share the same rugged IP67 case, the same tamper alarm and the same accelerometer. What separates them is how they are powered, whether they can use Wi-Fi to find themselves, and where you are allowed to fit them.

This guide explains the differences between the T2000-A, T2000-B and T2000-C, when the B's Wi-Fi earns its place, when the solar C makes sense, and what ATEX certification does and doesn't tell you. If you are still deciding between the T2000 and the smaller T1000, start with our T2000 vs T1000 comparison. If you already have one, skip to adding it to Trackpac.

The Short Answer

• T2000-A is the default pick. GPS and Bluetooth positioning, an 8000mAh battery that Seeed says lasts over a year at hourly updates, a -40 to +85°C range and ATEX certification.
• T2000-B is the A plus Wi-Fi scanning. Choose it when your assets spend time around buildings, in depots or indoors, where GPS struggles.
• T2000-C runs on a solar panel and a rechargeable battery. Choose it for kit that stays outdoors in daylight, and accept a narrower temperature range and no ATEX certification.

T2000-A vs T2000-B vs T2000-C Compared

Everything in the table comes from Seeed's T2000 documentation. Battery life figures are Seeed's, and as Seeed points out, real life depends on your interval, positioning mode and where the tracker is fitted.

What All Three Share

Every T2000 is the same 117 × 65 × 30mm, 180g box in a glass-fibre reinforced case, rated IP67. You screw it to a container or vehicle, strap it to an animal, or stick it on with 3M double-sided tape. Outdoors it finds its position with GPS, GLONASS, BeiDou and QZSS, and Seeed claims 5 to 10m accuracy. One unit covers every LoRaWAN region: you set the frequency plan in the SenseCraft app, EU868 for the UK and Europe.

All three have the tamper button on the back. Mount the tracker so the button is held in, and removing it raises a top-priority alarm that sends the position every minute for 3 minutes by default. It is on out of the box. All three also have a 3-axis accelerometer for start moving, end movement, motionless and shock events. That one is off by default ("Enable 3-axis sensor" in the app) because it uses more power, so turn it on if you want movement-triggered alerts.

None of them has a button. A supplied magnet does the job: tap it 4 times on the sensor area to switch on or off, and twice to turn Bluetooth on for the app. Each can also store up to 1,000 positions while out of coverage and send them when it reconnects, an option that is off by default.

The T2000-A: The Default Choice

For most outdoor assets, the A does everything you need. Plant parked on open sites, trailers in yards, containers on the move: all of them can see the sky, so GPS gives a good fix, and the A's 8000mAh battery means you fit it and leave it.

That battery is a primary lithium thionyl chloride cell, not a rechargeable one. Seeed quotes over one year with an hourly GPS fix and up to 7 to 9 years with longer intervals. The A is also rated from -40 to +85°C, which suits kit that sits in a frozen yard or bakes in the sun. Our T2000 battery life guide explains what moves you between those two figures.

When the T2000-B's Wi-Fi Matters

GPS needs a view of the sky. Inside a building, under a canopy or in a yard hemmed in by tall sheds, the tracker can search for the full GPS timeout and still come back with nothing. That costs battery and leaves a gap on the map.

The T2000-B adds a passive Wi-Fi scanner. It listens for nearby access points and reports up to 5 of them with their signal strength. The tracker doesn't work out the position itself: the platform has to look the access points up. Trackpac's location engine does that automatically, so you don't need to buy a geolocation API key or write any code.

The B is worth it for depots, warehouses, yards with buildings and customer sites in built-up areas. For kit that moves between indoors and outdoors, set the positioning strategy to "GNSS + Wi-Fi" so it tries GPS first and falls back to Wi-Fi, or "Wi-Fi + GNSS" to try Wi-Fi first and save battery. Wi-Fi is no help in an open field with no access points nearby, so for kit that never goes near a building, the A does the same job.

All three versions can also scan Bluetooth beacons. That only gives a position if beacons are installed at known points around your site, so it is something to plan rather than switch on. Talk to us if you need it.

When the Solar T2000-C Makes Sense

The C replaces the A's 8000mAh primary cell with a 4000mAh rechargeable battery and a 0.5W solar panel. Seeed describes the result as multi-year, low-maintenance running under regular sunlight and moderate uplink intervals. The key words are "regular sunlight".

It makes sense for assets that live outdoors in daylight: tower lights and equipment left on open ground, machinery parked in the open, or animals out in the fields. Mount it where the panel gets light and isn't shaded by bodywork. It makes much less sense on anything that spends its life inside a shed, under a cover or in the dark.

There are trade-offs. The C works from -20 to +60°C rather than -40 to +85°C, and Seeed rates charging at 0 to 45°C, so don't count on the panel topping up the battery in a frost. The battery is half the size, and Seeed doesn't publish a figure for how long it runs without sun. The C is not ATEX certified. And it has no Wi-Fi, so it is a GPS and Bluetooth tracker like the A.

ATEX on the T2000-A and T2000-B

Seeed states that the T2000-A and T2000-B are ATEX certified, which is relevant if your kit works in or near potentially explosive atmospheres. The solar T2000-C is not ATEX certified.

Seeed's wiki says only "ATEX certified". It doesn't publish the zone, equipment category or gas group. Before you fit a T2000 anywhere classified as a hazardous area, ask your supplier for the certificate, check the marking on the unit against your zone classification, and follow your own site safety rules. Don't assume an ATEX mark means it can go anywhere.

Which One for Which Job

A quick way to decide: start with the A. Move to the B if buildings get in the way of GPS, and to the C if the tracker lives in daylight and you're happy with a narrower temperature range.

Where to Buy and What to Check

Seeed Studio sells all three direct: T2000-A, T2000-B and T2000-C. In the UK, The Pi Hut stocks the T2000-A at £48 including VAT at the time of writing (October 2026). It ships within the UK only, because of the lithium battery. The Pi Hut doesn't list the B or C, so order those from Seeed. Our SenseCAP T2000 page has the specifications and links in one place.

Before you order, check two things. First, how you will mount it: the tamper alarm only works if the button on the back is held in, so plan for screws or a strap on a flat surface. Second, coverage. The T2000 has no SIM and needs a LoRaWAN gateway in range. Seeed quotes up to 9.6km in open country, but real range depends on gateways and terrain. Our guide to checking LoRaWAN coverage in the UK explains how to find out.

Adding a T2000 to Trackpac

The setup is the same for all three versions and they all use the SenseCAP T2000 device type. The Trackpac network is a private LoRaWAN network that roams onto Helium and other public LoRaWAN networks, so where there is coverage you don't need your own gateway or network server. Trackpac decodes everything the tracker sends; on an A or C, there are simply no Wi-Fi scans.
