Humirel HPP805C031 Relative humidity module Datasheet

RELATIVE HUMIDITY MODULE
HM1520LF
Compliant with RoHS recommendations
Based on the rugged HS1101LF capacitive humidity sensor, HM1520LF is a dedicated humidity transducer
designed for measurements at low humidity. Direct measurement of dew point or water concentration can be
easily obtained in really cost effective conditions. Direct interface with a micro-controller is made possible with the
module’s linear voltage output.
MAIN FEATURES
Tubular form for through wall mounting
Product free from Lead, Cr(6+), Cd and Hg
Not affected by water condensation
Full interchangeability
Typical 1 to 1.6 Volt DC output for 0 to 20% RH at 5 V DC supply
Calibrated, linear voltage for easy electronic interface
Controlled temperature dependency
Ratiometric to voltage supply

HM1520LF Preliminary Specification when used from 1 to 30%RH
Those equations can be used above 30% RH and allow to obtain an over all accuracy as described
in page one of this document in all the humidity measuring range
Temperature (in the range 0 to 50°C) does not affect HM1520LF measurement when used from 1 to
30% RH. No temperature compensation is required.

IMPORTANT NOTICE :
HM1520LF is based on HS1101LF capacitive sensor and thus
is fully useable on a large range of relative humidity ( 1 to 99% RH). In that range,
HM1520LF presents a typical accuracy of +/-5% RH at 55% RH.)
However HM1520LF is a dedicated module for humidity measurements at low Relative Humidity
levels.
Thus, HM1520LF is also well adapted to measure water concentrations (ppm) or low dew
points when associated with an ambient temperature probe.
HM1520LF features an optimized accuracy for water concentration below 6000 ppm water or
0°C dew point at 23°C (equivalent to 20% RH).
