· With a special chip design, it can measure the target distance within a range of up to 4.5m, with a measurement accuracy of ± 3%.
· Highly integrated miniature dToF SiP with dToF SoC and VCSEL emitters and optics in a compact package as small as 4.4 × 2.4 × 1.0mm.
· Based on self-developed SPAD with high consistency, excellent performance stability is obtained to meet the needs of more different application environments.

Recently, PolarisIC, a leading depth sensing and low-light imaging chip design company in China, announced the launch of a new single-photon dToF sensor micro-module DTS6007M. This is a single-channel dToF (direct time of flight) SiP micro-module, based on the high-performance SPAD detector and dToF SoC developed by PolarisIC, and integrated with VCSEL emitter and optical components, the comprehensive performance has reached the industry-leading level, and can be widely used in mobile phone laser-assisted focusing. Smart home areas such as sweeper, AGV obstacle avoidance and wall sensing, smart door lock and bathroom user detection, as well as capacity detection of inventory, parking space, liquid, etc.

I. Main advantages and characteristics
DTS6007M is a popular dToF depth sensing sensor built by PolarisIC for consumer electronics, smart home, Internet of Things and other fields. The sensor and functional circuit are fully integrated in the chip, and the integration of emission components and optical components is realized at the module level, forming a SiP with complete dToF functions.

The product uses a general I2C interface for communication, and has the characteristics of miniaturization, easy use, low cost and so on.
In addition, the DTS6007M has the following advantages:

II. Typical application
With many unique advantages, the DTS6007M micromodule can be used in a wide range of scenarios:

1.Mobile phone laser-assisted focusing
How to focus quickly and image clearly in dark light conditions has always been one of the pain points faced by smartphones in photography. dToF laser focusing technology not only has high-precision ranging performance, but also has excellent anti-ambient light interference ability, which can quickly achieve precise focusing in dark light, eliminating the tedious manual debugging of users.

2.Smart Home
In the field of smart home, dToF sensor can be widely used in cliff detection of sweeper, wall sensing, user detection of smart door lock, bathroom faucet, etc.

Sweeper Cliff Detection and Wall Sensing
The sweeper is equipped with a dToF sensor, which can not only accurately detect the distance between the sweeper and the cliff area, so as to achieve rapid obstacle avoidance, but also make the sweeper have super anti-environmental interference ability, and can work along the wall without interference.

User detection of intelligent door lock
The dToF sensor is installed on the face recognition intelligent door lock, which can realize the user detection at a certain distance in front of the door to save the power consumption of the door lock.

User detection of bathroom and faucet
The dToF sensor is installed on various smart home faucets such as bathroom, which can accurately sense whether there are people approaching, so as to realize the functions of automatic water outlet and flushing.

3. Capacity management
In some scenarios of factory automation devices and capacity management, it is necessary to use sensors to monitor the location capacity of supermarket containers and warehouse goods, the capacity of parking spaces, the capacity of trucks and containers, and the location of liquids in water tanks and various containers. Loading dToF sensors in these scenes can achieve long-distance, accurate and ultra-high-speed ranging, which has strong anti-environmental interference ability, can reduce manual monitoring activities, accurately measure capacity, and effectively improve the deployment efficiency of personnel and management.
