AS-L1S Laser Rangefinder — 40 m Module with RS485/UART Interfaces
AS-L1S — compact laser module for accurate distance measurement up to 40 meters with an error of ±1 mm. Used in industrial automation, tank liquid level control systems, warehouse logistics, robotics and position control. A universal set of interfaces TTL, UART, RS485 and RS232 allows integration of the module with any platform — from Arduino and Raspberry Pi to industrial controllers and SCADA systems.
Main Parameters
- Measurement Range: 5 mm — 40 m
- Accuracy: ±1 mm (across full range)
- Measurement Frequency: up to 20 Hz (50 ms per cycle)
- Single Measurement Time: 0.3-3 seconds
- Laser: 635 nm (visible red, Class II — safe for eyes)
- Power Supply: 5 V DC, consumption up to 200 mA
Applications
The AS-L1S module is a universal solution for tasks requiring non-contact distance measurement with high accuracy:
- Liquid Level Control — alternative to float and magnetostrictive level gauges, especially for aggressive or hot environments
- Industrial Automation — positioning of machine tools, conveyors, manipulators
- Warehouse Logistics — cargo dimension determination, stack height control
- Access Control — object detection in gates, barriers, lift systems
- Robotics — navigation, obstacle avoidance, mapping
- Geodesy and Construction — room measurement, geometry verification
Advantages of Laser Measurement
Compared to ultrasonic sensors, the AS-L1S laser rangefinder provides:
- Accuracy 5-10 times higher — ±1 mm versus ±10-50 mm for ultrasonic sensors
- Narrow measurement beam — point measurement without blur (ultrasonic has 15-30° cone)
- Operation at long distances — up to 40 m (ultrasonic typically up to 5-10 m)
- Independent of air temperature and composition (ultrasonic requires sound velocity compensation)
- Visible red beam simplifies aiming during setup
Integration
The universal set of interfaces makes the module compatible with virtually any control system:
- TTL/UART — direct connection to microcontrollers Arduino, ESP32, STM32, Raspberry Pi
- RS485 (Modbus RTU) — industrial PLCs, process automation systems
- RS232 — legacy but still common industrial equipment
Documentation and code examples are provided. Software customization for specific customer requirements is possible.
Delivery and Support
The AS-L1S module is in stock, shipment on the day of payment via Nova Poshta, CAT or shared transport throughout Ukraine (1-3 days). Manufacturer warranty — 12 months. Technical consultations on connection and integration — free from Gerkon engineers. Export through NOVA GLOBAL to Kazakhstan, Moldova, Georgia and other countries.

SHIPPING INFORMATION FOR UKRAINE
Our company is committed to fast shipping and delivery throughout Ukraine. We work with carriers that offer the best balance of price and quality, including:
NOVA POSHTA
1-3 days. Delivery speed depends on your location. After placing your order and payment, we ship the same day or the next.
SAT
Delivery time 3-5 days. Speed depends on the distance between sender and recipient. This is the most economical option compared to Nova Poshta.
DELIVERY
Shipping takes 4-7 days. This is the slowest method, but its advantage is the low cost.
FREIGHT POOLING
Shipping is done via shared transport through a dispatcher. Finding a vehicle takes 1-2 days; speed depends on the destination (major cities are faster, remote villages slower). This method is cheaper than the carriers listed above.
We work throughout Ukraine, and on request can arrange delivery via another courier service not on our list.
After placing your order in our online store, please provide the following information for delivery to your region:
- Recipient's full name
- City or town
- Number of the nearest warehouse (if shipping via courier services)
- Mobile phone number
Once the goods are shipped, we will provide you with the waybill number. When picking up your order, please bring your passport and the waybill number.
NOTES:
- The seller is not responsible for the operation of postal / courier services.
- Shipments are insured for full value; in case of damage the carrier is obligated to compensate you in full.
- Shipping costs are paid by the buyer (or by mutual agreement).
- If the requested product cannot be supplied, an equivalent replacement will be offered upon your approval.
If you couldn't find an answer to your question in this section, please contact us for more detailed information.
PAYMENT METHODS
After placing an order for a selected product in our store, we verify stock availability and confirm with you. Payment can then be made using one of the following methods:
- Bank transfer to the company account (VAT included).
- Cash on delivery (payment upon receipt).
Before paying via bank transfer, please contact us to confirm product availability.
Cash on delivery is processed at the carrier's warehouse. The service fee is 2% of the total + 15 UAH for payment processing. For an order of 1000 UAH you will pay 35 UAH for this service plus the shipping cost.
The second method is more reliable as you can inspect the goods on the spot, but it is also more expensive, so before paying you may want to consider which method suits you best.
If payment is received by 12:00, we ship the same day; if payment arrives later, shipping is processed the next day.
For any questions about payment, please contact us — if you haven't found an answer to your question, we will provide more detailed information.
