Our sensors have a battery inside. When the battery is empty, the sensor won't measure and send any data to the platform anymore. So it is important to recharge your battery before this occurs. The battery is empty when the voltage reaches 3.2V. Read the following article to display the voltage level.
There are four different battery set-ups with their own charging method. This article will explain every way of charging:
Charing your connect
Charge your sensor by using a wireless charger
Charge your sensor by using the wired charger
Replace the batteries of the sensor
Charging your connect
All of our new connect & sensors use a wired charger. If you are using an older sensor, use one of the other listed charging methods.
Here is how to charge the connect step by step:
1. Unscrew the cap from the power port (the lightning bolt symbol)
2. Attach the power supply plug to the connect
3. Plug the power supply into the wall socket
4. Check the charging status on the connect with the help of the led.
- Red: the connect is powered
- Orange: the connect is charging
- Green: the connect is done charging
6. Green light? Unplug the power supply from the wall socket
7. Disconnect the power supply plug from the connect
Charge your sensor by using a wireless charger
Most of our previous sensors versions can be wirelessly charged. If the grey box from the sensor only has an output where the sensor connects and no black charging port at the bottom, the sensor can be charged wirelessly. Charge the sensor simply by putting the sensor on your wireless charger. Within 4-6 hours the sensor is ready for another year. The sensor can be charged with any wireless Qi-certified charger but we recommend using the Choetech T511. If you need a wireless charger you can request this by contacting 30MHz Support.
How to charge your sensor step by step:
For the Spigen F303W (looks like a black Z).
- Plug the wireless charger into a power socket. This will cause the lights of the charger to blink a few times to signify that it has power.
- Place the sensor on the charger as depicted below (the 30MHz sticker must show when the sensor is placed on top of the charger).
- The charger will show a blue light if it is charging.
- Charge the sensor for 4-6 hours.
- When the blue light has changed to both blue and red the sensor is fully charged.
- The sensor is ready to measure again!
For the Choetech T511 (looks like a black plate).
- Plug the wireless charger into a power socket. This will cause the lights of the charger to blink a few times to signify that it has power.
- Place the sensor on the charger as depicted below (the 30MHz sticker must show when the sensor is placed on top of the charger).
- The charger will show a blue light if it is charging.
- Charge the sensor for 4-6 hours.
- When the sensor is done charging, the blue light will turn off.
- The sensor is ready to measure again.
Tips:
- Not sure if the charger is working? Try to charge your phone. Some phones can be charged using these wireless chargers. Please make sure before trying that your phone can be charged this way.
Charge your sensor by using the wired charger
Some sensors need to be charged with the 30MHz wired charger. These sensors can be recognized by the presence of a charge port (see picture below). If you need a wired charger you can request this by contacting 30MHz support.
Charge your sensor with a wired charger, step by step:
- Plug the charger in a power socket.
- Take off the black cap from the charger port.
- Attach the charger to the charger port.
- Charge the sensor for 4-6 hours.
- Put the black cap from the charger port back on.
- Sensor is ready to measure again.
Replace the batteries of the sensor
The only sensor where batteries need to be replaced manually is the temperature/humidity sensor version SHT25 (see image below). The voltage range for the SHT25 sensor is between 3.5V (full) and 2.6V (replace).
We recommend replacing the empty batteries with Energizer Ultimate Lithium AA batteries, these batteries have an extended temperature range compared to standard AA batteries.
