FAQ: Improving Sensor Signal Strength & Connectivity
1. What is sensor signal strength and why is it important?
Answer:
Sensor signal strength measures the quality of the communication between your sensor and the sensor gateway. Strong signal strength ensures accurate readings and efficient battery use. Poor signal strength can cause missed data and faster battery drain because the sensor works harder to maintain connectivity.
2. What causes poor signal strength?
Answer:
Poor signal strength can be caused by:
Obstacles: Thick walls, metal surfaces, and other materials that block or absorb radio waves.
Interference: Devices or materials that disrupt radio signals.
3. Where can I find a sensor’s signal strength?
Answer:
Jolt Mobile App:
Go to the Sensors page, select the desired sensor, and view the last recorded signal strength. For a detailed analysis, use the web portal.Jolt Web Portal:
Navigate to the Sensors Dashboard, select the location and sensor, then choose the Signal Strength filter from the Reading Type options.
4. How can I improve sensor signal strength and connectivity?
Answer:
Minimize Interference:
Test Range: Move the sensor closer to the gateway (within 10-15 feet) without obstacles. If the signal is still poor, contact Jolt support for further assistance.
Optimize Gateway Placement:
Elevate the Gateway: Install the gateway as high as possible to reduce interference, avoiding increased obstacles between the gateway and sensors.
Relocate the Gateway: Move the gateway closer to areas with poor signal, like walk-in freezers, using a longer Ethernet cable if needed.
Adjust Gateway Antenna:
Laird (Blue) Gateways: Position the long LoRa antenna vertically (up or down).
Multitech Gateways: Point antennas outward if mounted to a wall. If using a different antenna, keep it vertical even if mounted to a wall.
Utilize Sensor Probes:
Place Sensors Strategically: For sensors with probes, place the sensor in a location with better signal and extend the probe into areas with higher interference. For instance, place Laird (Blue) sensors outside a freezer while extending the probe inside.
Additional Hardware:
Consider Extra Gateways: If signal issues persist, adding more gateways in areas with poor signal might help. However, try the above solutions first to reduce interference.
5. What should I do if I still have signal strength issues?
Answer:
If you've followed all the steps and still experience problems with signal strength, contact Jolt support for further assistance.
