The ALTA wireless light meter is ideal for museums and art galleries as it enables you to record frequency readings of indoor lighting. Using the lux (luminescence/unit area) metric, the wireless light meter, one of the best light meters in the market features a range between 0 to 83,000 lux. The ALTA light meter is best suited for light sensitive applications and offers accurate and real time light monitoring.
The wireless light meter offers numerous customization options that enable you set custom notifications via SMS, email, and automated voice calls. You can even customize the frequency reading as per your requirement and the location where the light meter is installed.
ALTA – The Foremost Enterprise-Grade IoT Solutions Provider
Unlike other sensors in the market, our sensors are designed to offer increased operational range, which is up to 3 to 4 times greater than others. Our state-of-the-art technology enables the sensors to increase the non-line-of-sight range by up to 1,200+ feet, especially through walls. The extended range is effective on up to 14 standard construction walls.
ALTA sensors make use of Frequency-hopping Spread Spectrum (FHSS) that provides enhanced interference protection against nearby wireless devices, thus offering uninterrupted services. We have also incorporated the latest power management system into our sensors to offer enhanced battery life for all our products.
Battery life duration:
- Coin cell sensors: 3+ years
- Industrial and AA sensors: 12+ years
ALTA takes security of the data and the device very seriously. All our sensor products feature Monnit’s highly secured Encrypt-RF® Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption. This high level of encryption ensures that the data is protected at all communication points, from the sensor to the gateway, the gateway to software, and during the return journey back to the sensor.
ALTA sensors are embedded with on-board storage that significantly reduces any chances of data loss. In case of communication loss with a wireless gateway, the wireless light meter automatically timestamps and stores the messages (upto 512 messages). Once communication is restored, the messages are sent to gateway.
Reasons for communication loss:
- Loss of the Internet
- Power cut
- Senor out of range
To ensure that our sensors work at peak performance levels, ALTA offers over-the-air (OTA) updates that bring new features, fixes, and software patches.
In a standard configuration, the wireless light meter comes with two 1.5 V AA batteries (replaceable). However, the ALTA sensor is also available in a power line option that comes with a barrel power connector, making it compatible with a 3.0 – 3.8 V power supply. To ensure consistent operations, the line version of the wireless light meter is also backed up with two standard 1.5 V AA batteries.
