Hello,
I have a few ncd devices (https://store.ncd.io/product/industrial-long-range-wireless-temperature-humidity-sensor/) that work perfect for days in our lab, reporting readings every minute. The problem is when i take it to the client it stops sending reading every minute but sends random readings (may stay hours without any reading received).
Other devices work ok, but 5 of them i cannot make them to work perfectly.
How can i diagnose the cause of the problem?
What would make them work perfect in my lab and not in the client when similar devices work there?
Thanks in advance
Hi @cesararaujo Are you in the European area? This question is because there may be noise interference affecting the NCD sensor transmission.
You can check the counter value between transmissions to see if the sensor is sending packets correctly, but packets may be getting lost during wireless transmission.
Could you share us some screenshots of this value?
Thank you,
Eduardo M.
Yes European area, Portugal to be more precise.
Where can i check the counter?
All the sensors are on a table apart 1 meter from the receiver.
Hi @cesararaujo The “counter” values comes with the sensor data, here is an example:
{
nodeId: 0
firmware: 1
battery: “3.11”
battery_percent: “94.24”
counter: 13 ← This one
sensor_type: 1
sensor_data:
{
temperature: 31.45
humidity: 60
…
}
You can monitor this value when incoming new sensor data, this value must be consecutive between each transmission. If it is not consecutive, data is probably being lost during wireless transmission due to noise.
Thank you,
Eduardo M.
is probably being lost during wireless
Thank you.
You’re welcome! Feel free to let us know if we can support you with anything else.
Thank you,
Eduardo M.
I will test monday and report back to you 
Thanks in advance
Hello, I have new data.
I have few sensors working fine but 3 of them have this weird behavior at about a meter from receiver.
I attach here raw data of one of the problematic sensors.
When i was at the client configuring all the sensors
i formatted the raw information for more easy view as “raw sensor data - packet counter”

What can be causing this at about a meter from the receiver? all in a table.
Hi @cesararaujo In order to confirm:
- What is the actual transmission rate value for each sensor?
- Could you put the sensors a bit apart from each other and see if the issue persists?
- Are you using a USB modem to see the incoming data?
Thank you,
Eduardo M.
Hello,
1 - They should report every 60 seconds.
2 - Yeah issue persists.
3 - I am using a zigbee to tcp/ip receiver, so a network receiver. (https://store.ncd.io/product/industrial-iot-wireless-ethernet-modem/)
Thanks
Hi @cesararaujo We can see that the actual NCD Sensor battery voltage is ~2.74V. This could be the cause of packet loss during transmission. Could you try changing the batteries for new ones and try again?
Note: If the battery voltage falls below 2.8V, it is advisable to replace the battery.
Thank you,
Eduardo M.
