Smart city devices operate outdoors and often unattended. They include sensors on street lighting poles, parking terminals, air quality monitoring stations and waste containers with fill-level sensors. They have to withstand the weather, run for years on a battery and transmit data reliably. That is why the wireless technology, power consumption, IP rating and temperature resistance are decisive.
On this page you will find components for street lighting, parking, traffic, air quality monitoring, waste management and shared mobility. From communication modules and antennas through sensors and batteries to displays, industrial PCs and network equipment.
Most devices in a city send small amounts of data and need low power consumption. Quectel offers NB-IoT, LTE-M and 5G RedCap modules, for example multimode LTE Cat M1 and Cat NB2 modules with integrated GNSS. For private networks without an operator, there are LoRa modules from HopeRF, IMST and Aurel for both the 868 MHz and 2.4 GHz bands. Antennas from 2J Antennas and Antenova for LTE, NB-IoT, Wi-Fi and Bluetooth complete the signal path.
For a sensor without a mains connection, the battery determines its service life. Lithium batteries from Fanso and EVE Energy include 3.6 V Li-SOCl2 cells as well as 3.0 V Li-MnO2 cells with capacities of up to 12 Ah. For rechargeable devices, we stock EEMB 3.7 V Li-Ion and Li-Po rechargeable batteries. Mains-powered devices are covered by TRACOPOWER AC/DC power supplies with metal housings and non-isolated DC/DC converters for inputs up to 36 V.
Monitoring stations need accurate sensors with long-term stability. Gas sensors from Sensirion, Figaro and Nissha FIS measure CO2, ozone, methane, CO and volatile organic compounds (VOC). Sensirion particulate matter sensors detect the PM1.0, PM2.5, PM4 and PM10 fractions, and some types also measure humidity, temperature, VOC and NOx in a single module.
Sensor and communication modules connect to smart luminaires through a standardised interface. TE Connectivity LUMAWISE connectors for LED street lighting include four-pole receptacles to Zhaga Book 18 with IP66 protection, rated 30 V and 1.5 A. The control electronics can be completed with the Wi-Fi, Bluetooth and LoRa modules from the communication section.
Parking machines and access terminals read tickets, cards and codes on mobile phones. This is the job of Opticon 2D scanners with IP65 protection and an RS232C interface, and Elatec TWN4 MultiTech 2 HF RFID readers for 13.56 MHz. For access control systems, ACM RFID cards and key fobs for 125 kHz are available.
Information boards and control panels use Display Visions graphic LCD modules from 128 × 64 resolution and touch TFT displays from Display Visions and 4D Systems up to 4.3". Computing power for traffic management and surveillance comes from AAEON and Lexsystem industrial box PCs, for example DIN rail box PCs for -30 to 60 °C. Rugged AAEON tablets with 10.1" and 11.6" screens are designed for field use.
Device data is collected over a local network or a mobile gateway. Unmanaged 8-port Hirschmann industrial switches and LTE Cat 4 gateways are available, both for DIN rail mounting. Lantronix embedded modules offer Wi-Fi 6, Ethernet and Bluetooth 5.4. For simple Wi-Fi and Bluetooth connectivity, there are Espressif ESP32 modules.
The Quectel BG770A LTE LPWA communication module is built specifically to address PCB space constraints without sacrificing performance. It brings together an ultra-compact footprint, lightweight design, minimal power draw, and a built-in GNSS receiver, all while supporting Cat M1 and IoT NB1/NB2 bands across a wide supply voltage range.
Sensirion offers three series of mass flow controllers. But which one to choose? We have compared the features and benefits of the latest Sensirion SFC5400, SFC5500 and SFC6000D series so that you can choose the best solution for your device.
Sensors from Piher measure the rotation angle or linear position. The durable and robust design provides more than 50 million rotation cycles or virtually unlimited life for 2-piece rotary and linear sensors. They are made for harsh environments with the ingress protection of IP69K. (reading for 3 minutes)
