Ever circled the same block three times looking for a parking spot? Multiply that by thousands of drivers, every day, in every European city, and you get a huge chunk of urban traffic that has nothing to do with actual travel. By 2026, more cities are fixing this with LoRaWAN parking sensors that know, in real time, exactly which spaces are free.
How LoRaWAN Parking Sensors Actually Work
A parking sensor has one simple job: tell you if a space is taken. It does this by measuring distance. If the distance is short, something is blocking it — usually a car. If the distance is long, the space is empty.
Two types of sensors are common. The Milesight EM400-TLD uses a ToF laser to measure distance very precisely, which works well for fixed or overhead mounting. The Milesight EM400-MUD uses ultrasonic sensing instead, and it's built to do more than just parking — it can also detect liquid levels, tilting, and even fire alarms. That's why shopioT lists it under a few different collections, not just parking.
| Feature | EM400-TLD | EM400-MUD |
|---|---|---|
| Sensing technology | ToF laser distance | Ultrasonic distance |
| Best suited to | Precise fixed or overhead mounting | Multi-purpose deployments |
| Extra functions | Level & distance monitoring | Liquid level, tilt, fire alarm detection |
| Battery | Long-life battery powered | Up to 10 years on dual 9000mAh batteries |
Either sensor sends its data over LoRaWAN. That means no digging trenches for cables and no per-device cellular bills. One gateway can cover a large lot or several blocks of street parking on a single private LoRaWAN network.
Why Battery Life Is the Real Deciding Factor
Installing a sensor under or near a parking space isn't easy — it usually means lane closures and permits. You want to do that job once. The EM400-MUD is built for up to 10 years of use on its dual 9000mAh batteries, which makes a city-wide rollout realistic instead of a constant maintenance headache.
From Occupancy Data to Reduced Congestion
Knowing a space is free is only step one. The real payoff comes from what a city does with that information.
None of that works without sensors feeding accurate data through a well-placed LoRaWAN gateway — the piece that turns scattered sensors into one live map of the city.
Planning a Rollout
Most cities do better starting small — one garage, one busy street, one known trouble spot — instead of trying to cover the whole city at once. That lets your team check gateway coverage and data accuracy before scaling up. For sizing gateways and frequency planning at larger scale, the principles in our guide to LoRaWAN deployment in Europe apply directly.
shopioT works directly with city and business buyers on this kind of rollout. You can read more about us on our about page or check common questions on our FAQ page before requesting a quote.
Sensors alone won't fix congestion, but they're the piece that makes every other fix — routing, pricing, enforcement — actually work with real data instead of guesswork. That's why more 2026 smart-city budgets include LoRaWAN parking sensors as a standard line item.
Frequently Asked Questions
How does a LoRaWAN sensor know a parking bay is occupied?
It measures the distance to whatever's below it. A short distance usually means a car is there; a long distance means the space is empty. The EM400-TLD does this with a laser, and the EM400-MUD does it with ultrasonic sensing.
How long do battery-powered parking sensors last?
The EM400-MUD is rated for up to 10 years on its two 9000mAh batteries, so you won't need to visit it often.
Can these sensors do anything besides detect parking occupancy?
Yes. The EM400-MUD can also handle level detection, tilt monitoring, and fire alarms, which is why it shows up in more than one shopioT collection.
Can sensors be pre-configured for our city's network server before delivery?
Yes. shopioT's engineering team can set them up for network servers like The Things Stack or ChirpStack before shipping.
Is a formal quote available for a city-wide procurement?
Yes. shopioT's CyRIC IoT division handles B2B and bulk orders.
Start Small, Prove It Works, Then Scale
Smart parking isn't about adding more technology for its own sake; it's about giving cities the real-time data they need to fix a problem drivers deal with every day. Pick one trouble spot, instrument it properly, and let the data make the case for the next phase.
