7.4.4 Example commands and operation

7.4.4.1 Read measurement data from device

This command requests the APC1 to send the latest set of measurement results (64 -byte structure). Make sure the device is in Measurement mode with passive communication (Default after POR). Send the following protocol: Table 16: Communication protocol to request the latest set of measurement results Host command 0x42 0x4D 0xE2 0x00 0x00 0x01 0x71 Device answer 0x42 0x4D FrameLengthH/L PM1.0H/L PM2.5H/L … Version ErrorCode ChecksumH/L The device responds by sending a 64-byte structure (see “Device answer”) containing the latest measurement results. Repeat this command whenever there is a need for new measurement data. Note that the maximum update rate of the 64-byte structure is 1Hz.

7.4.4.2 Set Idle mode

8 Integration and operation

8.1 General

• Do not remove the outer metal shell of the APC1.
• Do not attempt to open the module.
• Protection must be added if the sensor is used in the following conditions: o PM concentrations ≥300μg/m³ for more than 50% of combo lifetime o PM concentrations ≥500μg/m³ for more than 20% of combo lifetime o Kitchen environment o Occasional water mist conditions such as in bathroom environments.
• Refer to section 3 “Intended use” for further details.

8.2 Combo orientation

To ensure proper functioning throughout the entire lifetime, the following guidelines for combo orientation must be met: Figure 6: Recommended combo orientation

20 APC1 Datasheet SC-001581-DS-3 Version 1.0 / 2022-04-11 / Production CONTENTS PAGE

8.3 Integration into a host system

8.3.1 Mechanical Integration

• Keep inlet and outlet plane of both, APC1 and host system as close as possible to each other. If required, use suitable air guides and/or ductwork with sealants to avoid short- circuits of air flows.
• Host system inlet and outlet must not be smaller than APC1 inlet and outlet.
• To avoid false results, protect/shield inlet and outlet from output air flow of ventilation system or air cleaner.
• Install APC1 at least 20 cm above the floor in order to prevent blocking by larger particles or flock dust.

8.3.2 Temperature and humidity compensation on system level

For precise temperature and humidity readings, the APC1 is equipped with a temperature and humidity compensation algorithm on module level . Due to excess heat from external/host components, some integrations require further temperature and humidity compensation. This section describes how to determine and comp ensate such offsets and correct for consequential humidity errors.

8.3.2.1 Determining and compensating the temperature offset

The following procedure uses a single temperature measurement point to determine the APC1 temperature offset, induced by a host system. Required items:

• A temperature reference TRef (e.g. ScioSense ENS210 evaluation kit on flex-foil).
• A system with an integrated APC1, logging the device’s temperature reading T Sys. Important Note: As the device’s temperature reading TSys, it is recommended to use the compensated temperature value T-comp from the 64-byte data structure (see Table 14, Register 0x22). Do not use T-raw. T compensation equation: 𝑇𝑅𝑒𝑓 = 𝑇𝑆𝑦𝑠 + 𝑇𝑂𝑓𝑓𝑠𝑒𝑡 Compensation procedure: 1. Setup the temperature reference and system under calibration in a thermally stable environment at a typical environmental / operating temperature. 2. Wait for the temperature readings to stabilize (APC1 and reference) ; thereafter start recording.

APC1 Datasheet SC-001581-DS-3 Version 1.0 / 2022-04-11 / Production 21 CONTENTS PAGE Note: For the sake of highest accuracy, it is advisable to carry out a series of experiments and/or log the data for a longer duration while stable. 3. For highest precision , average the recorded temperature values before calculating the difference between system and reference with the following equation: ∆𝑇 = 𝑇𝑂𝑓𝑓𝑠𝑒𝑡 = 𝑇𝑅𝑒𝑓 – 𝑇𝑆𝑦𝑠 with 𝑇𝑅𝑒𝑓: Averaged temperature value of the temperature reference 𝑇𝑆𝑦𝑠: Averaged temperature value of the system under calibration 4. Compensate the temperature reading by subtracting the determined offset: 𝑇𝐶𝑜𝑚𝑝 = 𝑇𝑆𝑦𝑠 + 𝑇𝑂𝑓𝑓𝑠𝑒𝑡 = 𝑇𝑆𝑦𝑠 + (𝑇𝑅𝑒𝑓 – 𝑇𝑆𝑦𝑠)

8.3.2.2 Correcting the temperature-offset induced humidity error

Since (per definition) the relative humidity output is a temperature-dependent signal, it requires a temperature-offset-dependent correction, provided the temperature offset is other than zero. Once the T-compensation is done, the humidity correction only requires an additional calculation according to the following equation: 𝑅𝐻𝐶𝑜𝑚𝑝 = 𝑅𝐻𝑆𝑦𝑠 ∗ (273.15 + 𝑇𝐶𝑜𝑚𝑝)/(273,15 + 𝑇𝑆𝑦𝑠) ∗ 10 ^ (𝑎 ∗ 𝑇𝑆𝑦𝑠/(𝑏 + 𝑇𝑆𝑦𝑠) − 𝑎 ∗ 𝑇𝐶𝑜𝑚𝑝/(𝑏 + 𝑇𝐶𝑜𝑚𝑝)) with 𝑇𝑆𝑦𝑠: T-comp temperature reading of the APC1 (see register 0x22 Table 14) 𝑇𝐶𝑜𝑚𝑝: Compensated 𝑇𝑆𝑦𝑠 temperature reading 𝑅𝐻𝑆𝑦𝑠: RH-comp relative humidity reading of the APC1 (see register 0x24 Table 14) 𝑅𝐻𝐶𝑜𝑚𝑝: Compensated 𝑅𝐻𝑆𝑦𝑠 relative humidity reading 𝑎: 7.5 (T ≥ 0°C); factor, defined by physical laws 𝑏: 237.3 (T ≥ 0°C) ; constant, defined by physical laws Example T-Compensation Assuming the above experiment shows the following results: 𝑇𝑅𝑒𝑓 = 21°𝐶; 𝑇𝑆𝑦𝑠 = 25°𝐶 → ∆𝑇 = 𝑇𝑂𝑓𝑓𝑠𝑒𝑡 = 𝑇𝑅𝑒𝑓 – 𝑇𝑆𝑦𝑠 = −4°𝐶 Meaning that the host system causes a temperature offset of an additional 4°C on the APC1, which needs to be compensated for by subtracting said 4°C from the APC1’s TSys reading: 𝑇𝐶𝑜𝑚𝑝 = 𝑇𝑆𝑦𝑠 + 𝑇𝑂𝑓𝑓𝑠𝑒𝑡 = 𝑇𝑆𝑦𝑠 + (𝑇𝑅𝑒𝑓 – 𝑇𝑆𝑦𝑠) = 25°𝐶 + (21°𝐶 − 25°𝐶) = 21°𝐶
